DENVER (AP) – The Denver Broncos once again found barely enough offense to go with their suffocating defense.

Jason Elam kicked two field goals, Tatum Bell ran for a short touchdown and Champ Bailey picked off another key pass as the Broncos defeated the winless Oakland Raiders 13-3 Sunday night.

The offense-challenged Broncos (4-1) haven’t allowed a touchdown in three home games and they’re the only NFL team since the 1934 Lions to start off a season by yielding just one TD through five games. Detroit shut out its first seven opponents that season.

The Raiders committed 13 penalties, including four false starts on backup right tackle Chad Slaughter, and fell to 0-5 for the first time since 1964. With Detroit, Tampa Bay and Tennessee all winning Sunday, the Raiders are the only winless team in the NFL.

Oakland has lost 11 in a row dating back to last season.

As is their style, the Broncos bent but didn’t break. Bailey picked off a pass at the Denver 1 in the first half and defensive tackle Michael Myers ended another promising drive by the Raiders when he scooped up LaMont Jordan’s fumble at the Denver 19 with 4:24 remaining.

Sebastian Janikowski’s 47-yard field goal following Robert Thomas’ recovery of Darrent Williams’ fumbled punt return pulled the Raiders to 13-3 midway through the third quarter. Even that was ugly. The Raiders’ 23-yard drive that ate up almost 61/2 minutes included two sacks and a fumble by quarterback Andrew Walter, which he recovered himself.

Thanks to Javon Walker, Bailey and eight whistles on the Raiders, the Broncos took a 13-0 lead into the locker room. With this Denver defense, that’s downright insurmountable.

Bailey had perfect position on Randy Moss and picked off Walter’s pass just before he tiptoed out of bounds. Last week, Bailey’s picko of Steve McNair’s lob pass in the end zone just before halftime helped the Broncos beat Baltimore, also 13-3.

Bailey’s interception came just two plays after Walter, making his third start in place of Aaron Brooks (injured right shoulder), hit Moss for a 51-yard gain to the Denver 28. The play covered nearly as many yards as the Raiders managed (57) on their first 22 plays.

In the first quarter, safety John Lynch punched away a pass to Moss in the end zone, and Janikowski’s 54-yard field goal attempt sailed wide right.

Two plays later, the Broncos went ahead for good.

Denver took over at its 44 and Jake Plummer pulled off a play fake before lofting a jump ball to Walker, who outleaped cornerback Nnamdi Asomugha and came down at the Raiders 2 for a 54-yard gain.

Bell took it in on the next snap for a 7-0 Denver lead with 39 seconds left in the first quarter – the first points the Broncos have scored in the opening quarter all season.

Elam kicked field goals of 51 and 22 yards in the second quarter for a 13-0 halftime lead. His second field goal came after fullback Cecil Sapp, replacing starter Kyle Johnson, who sprained his right ankle on the Broncos’ first series, dropped a wide-open pass while he was trotting in for an easy 4-yard touchdown.

Walker, who caught four passes for 75 yards, had a 29-yard gain on a double-reverse on the drive.

Things got so bad for the Raiders that Terdell Sands body-slammed Bell in the closing minutes and was whistled for a personal foul, Oakland’s 13th penalty.

The Raiders actually outgained the Broncos 244 yards to 235, but Walter was just 13-of-26 for 189 yards. Plummer completed 11 of 18 passes for 102 yards.

Art Shell’s return to the sideline this season hasn’t been smooth, and it’s only getting rougher. Oakland came into the game with the worst offense in the NFL, averaging 225.3 yards, and the Raiders suspended receiver Jerry Porter without pay on Saturday for conduct detrimental to the team.

Porter was inactive for the first four games after feuding with Shell and demanding a trade at the beginning of training camp. Porter was the Raiders’ leading receiver last season with 942 yards.

Notes: The Raiders’ worst start came in 1962, when they lost their first 13 games before beating Boston in the season finale, ending 19-game skid. … Broncos WR Rod Smith became the sixth player in NFL history to catch 100 passes against three or more teams. … Slaughter was inserted into the lineup after starter Langston Walker suffered an unspecified injury in the first quarter. … Shell fell to 11-2 against the Broncos.
