Teammates offered congratulations and condolences to Scott Dreisbach last night after the backup quarterback had rallied the Oakland Raiders to a preseason win for the second straight week but broke his leg while setting up the decisive touchdown.

Dreisbach led host Oakland for most of a 10-play, 77-yard drive capped by Tyrone Wheatley's one-yard plunge with 35 seconds remaining that gave the Raiders a 10-3 win over the penalty-prone Dallas Cowboys.

Dreisbach was tackled while trying to get to the sideline on a bootleg with 1 minute 45 seconds left. He landed on his right leg at the Dallas 5, grimacing in pain and then covering his face with his hands before being taken off the field on a cart.

"I heard it crack when I was hit, I actually thought it was both of them," Dreisbach said. "The doctor squeezed it and I heard it crack again."

Dreisbach, who was 8 of 12 for 111 yards, had been one of the biggest surprises of Oakland's training camp. A week earlier, he threw a touchdown pass with 1:38 left to give the Raiders an 18-17 win in St. Louis.

Dreisbach, signed as a free agent, probably would have had a good chance at winning the third-string job.

The Cowboys were plagued by penalties for the second consecutive game. Six days after being flagged 17 times for 149 yards in the loss to Cleveland, Dallas was penalized 11 times for 80 yards against the Raiders.

CHIEFS 22, TITANS 20: Todd Collins, trying to hold his job as third-string quarterback, finished a long third-quarter drive with his second touchdown pass of the game to spark Kansas City at home.

Elvis Grbac started for the Chiefs and was 7 of 10 for 73 yards, while backup Warren Moon didn't play as planned.

The Chiefs led 16-13 at halftime before Collins led a 12-play, 65-yard drive that ate up 5 minutes 13 seconds of the third quarter and ended with a two-yard touchdown pass to Ron Janes for a 22-13 lead. The Titans made it 22-20 with 1:34 to play on Kevin Daft's 20-yard scoring pass to Isaac Byrd that capped a 10-play, 76-yard drive.

Collins, fighting with rookie free agent Ted White (Howard University) for the third quarterback job, was 9 of 14 for 122 yards. Tennessee's Steve McNair was 6 of 11 for 66 yards with an interception. Neil O'Donnell was 10 of 17 for 73 yards.
