Crossing over.

No, not the television show geared toward contacting dearly departed loved ones. In the case of Class A football, it’s a concept that for one week only will resurrect some intriguing, long-forgotten gridiron rivalries.

And some that never really existed in the first place.

On the plus side, Waterville of Eastern Maine’s Pine Tree Conference and defending state champion Portland of the West will collide tonight in a meaningful game for the first time since 1980. Lawrence and South Portland, the two programs that met for the state championship in 1992 and 1996, also are reunited this evening.

Although the pairings were said to be made geographically, some of the Class A crossover games involving local teams aren’t as likely to accelerate the heartbeat. Lewiston travels south to Berwick to visit Noble, while Sanford makes the journey to Walton Field in Auburn to meet Edward Little. Mt. Blue hosts Westbrook, and Oxford Hills heads to Biddeford.

In more traditional fare, it’s a journey back to the days of the Mountain Valley Conference when Lisbon drops in on Jay in a game with early Western Class C playoff implications in the Campbell Conference. Oak Hill, Mountain Valley and Livermore Falls also hope to remain undefeated.

Here’s a closer look at the 11 local games:

Tonight’s games

Lisbon (1-0) at Jay (1-0) , 7 p.m.

Both teams had their way with an overmatched opponent last week. Lisbon showcased the east-to-west running prowess and hands of John Tefft (231 all-purpose yards, four TDs) in a 40-12 rout of Old Orchard Beach, while Jay QB Justin Wells welcomed Buckfield/Dirigo to varsity football with five TD tosses in a 56-18 triumph.

Wells (10-for-12, 188 yards in the opener) is arguably the most dangerous passer in Class C, and he has at least two terrific targets in Marc Kelvey and Ryan Dipompo. Tefft and Chris Kates will provide the most resistance in a relatively young Lisbon secondary. The Tigers will have to be balanced to win, though, and Greyhounds DE Tony Walker and LB Derek Roy are capable of sidetracking anyone’s rushing attack.

Wells (1-0) at Mtn. Valley (1-0), 7 p.m.

One game into the season, and as usual, there are no questions about the Falcons’ heart. Mountain Valley knocked off Leavitt in its opener, 19-18, despite accumulating only 102 yards net offense. Korey Staires (three interceptions) and Zach Fergola each scored a defensive touchdown. Aaron Robin and Travis Dragoon led a gang-tackling effort against the run.

Fergola made strides in his first start at QB, while Mountain Valley relied on a running back-by-committee approach that included Dickie Cote and Eric LePage. The Warriors blanked Morse, 14-0, with Tyler Stevens’ 88-yard strike to Billy Froncko providing most of the offense. HB Luke Sibley and FB Kirk Jones give Wells the potential of a prolific ground game.

Lewiston (1-0) at Noble (1-0), 7:30 p.m.

These crossover foes beat their opponents by a combined 95-6 last week. The Blue Devils racked up 490 yards, all on the ground, against Windham, with James Spaulding slashing his way to 234 and four TDs. FB George Foisy also had a long TD jaunt, and Jake Angelides returned a kick for a score.

The Knights already are on a different path than last year’s 0-8 campaign. RB Decota Cotten is a breakaway threat. Cotten and QB Miles Johnson operate behind a rugged offensive line that includes Jeremy Pillsbury and Sax Lynch.

Sanford (0-1) at EL (0-1), 7 p.m.

Both squads would like to file away forgettable opening games. Sanford’s offense, which struggled in a 40-0 loss to Noble, is rebuilding at the skill positions behind a veteran offensive line. Shane Fenderson, Matt Leck and Matt Delisle do the blocking for QBs Bill Pickering and Ryan Guillemette.

Defending PTC champion EL stumbled to a 42-14 loss at Bangor.

The Red Eddies still have some capable offensive holdovers from last year’s playoff march, however. RBs Chris LeClair and Chris Lemieux each rushed for TD last week.

Lemieux went 94 yards for his score. Senior linemen Jon Paul and Cory Cyr are among those hoping to provide extra time for QB Matt Bennett (4-for-18, 51 yards).

Oxf. Hills (1-0) at Biddeford (1-0), 7 p.m.

These two teams haven’t met since a home-and-home crossover series in the mid-1990s. Each won its opener the hard way, with Biddeford using two fourth-quarter special teams gems to turn away Portland, 13-12, and the Vikings dispatching Mt. Ararat in overtime, 28-21.

Sophomore TB Jimmy Bower (186 yards, 3 TDs) stepped into the spotlight for Oxford Hills. James Morin scored both TDs for the Tigers, who used a blocked punt by Mike Thibault and a long punt return by QB Phil Bourassa as the springboard to their comeback.

The key to both running games is a big, strong fullback: Kass Eells for Oxford Hills and Jacob Brown for Biddeford.

Westbrook (1-0) at Mt. Blue (0-1), 7 p.m.

The Mike Landry era at Westbrook began with a 26-12 win over Scarborough, helping the Blue Blazes match last season’s entire win total. RB Todd Thompson (133 yards, two TDs) led the offense, while LB Shawn McCurdy had four of the Blazes’ seven QB sacks.

It’ll be a tougher assignment in Farmington, where the senior-dominated Cougars likely aren’t in a good mood after a 33-27 overtime loss at Westbrook. RB Lance Meader (175 yards) and QB Garrett Lake (TD passes to Andrew Beaulieu and Peter Tinguely) headline the traditionally diverse Mt. Blue attack.

Winthrop (0-1) at Madison (1-0), 7 p.m.

It wasn’t an auspicious start for the Ramblers, who lost 37-0 at Livermore Falls and saw RB Derek Gray go down with an injury after averaging less than a yard per carry in the first half. QB Tavis Hasenfus and whoever runs the ball will need a more consistent effort from the front five, and seniors Chad Caron, Chris Lavigne, Tom Bridgham, Jon Mortimer and Shaun Halligan are capable of providing it.

Injuries and position changes have also impacted Madison, which blanked Traip, 28-0, on the road last week.

Justin Watt and Josh Paine are splitting the QB duties while Watt rounds into shape after a broken colarbone.

Converted QB Matt Stewart, now the featured back, scored a TD in his first regular-season game since knee surgery.

Buckfield/Dirigo (0-1)

at Boothbay (1-0), 7 p.m.

Well, at least the Buckfield/Dirigo co-op venture gets two of the toughest battles out of its way in this initial campaign.

There were high points in a 56-18 home loss to Jay, including two long scores by Scott Wetherell (73-yard catch, 26-yard run) and the running of Craig Langervin (13 carries, 74 yards).

Two-time defending Class C champion Boothbay appears rugged as ever.

QB Ryan Babcock threw a 98-yard TD to Mike Norton in his first start.

D.J. Holcomb scored on four of his seven carries in a 55-6 win over Cape Elizabeth, while Justin Wood added 131 yards and a score.

Liv. Falls (1-0) at OOB (0-1), 7 p.m.

LBs Matt Belmonte, Brad Bryant, Matt Brochu and Garrett Young shone in a new 4-4 defense that directed the Andies to an impressive 37-0 trouncing of Winthrop. Bryant rushed for 153 yards and scored three TDs.

QB Mike Perrone and RB Bobby Seavey (71 yards) led the Seagulls in a gutsy effort, albeit a 40-12 loss at Lisbon. OOB only suited up 18 players due to eligibility issues.

Saturday’s games

Leavitt (0-1) at Oak Hill (1-0), 1:30 p.m.

Leavitt coach Mike Hathaway was an assistant to Oak Hill’s Bruce Nicholas for several seasons, helping rebuild a Raiders program that is currently on the upswing. Oak Hill returned to Class B with a solid 26-7 win at Fryeburg behind the three-headed rushing attack of QB Adam Labbe, HB Kyle Harrington (150 yards) and FB Tony Poulin (84 yards, 3 TDs).The Hornets struggled to find their offensive identity in a 19-18 loss to Mountain Valley, with three QBs taking snaps. One of those passers, Chad Schrepper, was also the most effective tailback. QB Dustin Gilbert and FB Kyle Davis also are part of the plan, with Marcus Reny delivering crunching blocks. Reny is the Hornets’ leading tackler.

John Bapst (0-1) at Maran. (0-1), 1 p.m.

Neither team scored a point in the opening week of Eastern Class C action. Orono blanked Bapst, 29-0, while the Black Bears bowed to Bucksport, 44-0. Junior QB Luke St. Pierre leads Maranacook, which is back in the Little Ten Conference after going 11-1 in a developmental league the last two years.
