FOXBORO, Mass. (AP) – New England Patriots coach Bill Belichick officially announced the signing of offensive guard Brenden Stai at training camp on Monday, but would not confirm published reports that fullback Larry Centers had also agreed to terms.

“We’ve already made quite a few comments on (Centers),” Patriots coach Bill Belichick said, “So we’ll wait until if he gets here, or when he gets here.”

Patriots spokesman Stacey James had earlier confirmed that the team had spoken with Centers. The Boston Globe and Boston Herald reported Monday that the Patriots agreed to terms with Centers, who spent the last two seasons with the Buffalo Bills.

A message left for Centers’ agent wasn’t immediately returned Monday.

Centers, 35, has caught 808 passes for 6,691 yards and 27 touchdowns during his 12-year NFL career with Arizona, Washington and Buffalo. Belichick did not say when he was expected to arrive in Foxboro from his native Texas.

Stai, 31, agreed to a one-year contract. Terms were not disclosed.

“He’ll certainly get an opportunity to play, Belichick said. “We have good competition now at the guard position.”

The 6-foot-4, 318-pound Stai has played eight seasons in the NFL. He was a rookie starter at right guard for the Pittsburgh Steelers in Super Bowl XXX against Dallas. Originally a third-round draft pick from Nebraska in 1995, he spent five seasons with Pittsburgh and has since played for Kansas City, Jacksonville, Detroit and Washington.

“I’ve had an unusual career because twice, I’ve been traded a week before the season,” Stai said. “I’ve kind of developed a reputation for being able to go in and start within a week.”

Stai, who has started 96 of 105 career games, won’t be as rushed with the Patriots. Belichick sees his addition as a means to add depth and competitiveness on an offensive line that has had to cope with the loss of guard Stephen Neal to a shoulder injury, and the inactivity of starting tackle Kenyatta Jones and starting guard Joe Andruzzi as they recover from offseason surgeries.

Stai is also coming off knee surgery, having missed all but five games with the Redskins last year.

“You sit back and reflect upon how much you love the game,” he said of his inactivity. “At the time, I didn’t love it too much because my knee was absolutely torn up. Then as time wears on, you’re sitting on the sidelines watching the guys go through all the aches and pains. I felt it just as much as they did, and I wanted to get back in there.”

Also Monday, the Patriots announced the release of rookie safety Scott Farley, who was signed as an undrafted free agent on May 9.
