QB leaves in first half after struggling
Tuiasosopo made his first NFL start in place of 2002 league MVP Rich Gannon, who injured his shoulder on Oct. 20 against Kansas City. Mirer made his first appearance since playing one game for San Francisco three years ago.
Gannon traveled with the team to Detroit, but was put on the inactive list before the game.
Tuiasosopo was 6-of-11 for 65 yards, with an interception on his second pass.
On Oakland's third drive, he bobbled a snap, then ran up the middle and fumbled when Boss Bailey hit him. Raiders center Barret Robbins recovered the fumble. Trainers then worked on Tuiasosopo's left knee, but he stayed in the game for two more possessions. The second one ended with a sack.
He walked out of the training room awkwardly with a brace covering much of his left leg.
"We did an X-ray and it's at least a sprained ligament," Tuiasosopo said. "We won't know for sure what it is until (Monday)."
Before Tuiasosopo nearly rallied the Raiders to a win against Kansas City, he had thrown just six passes this season, none last year and four as a rookie in 2001.
