Quinn only threw three passes against the Ravens, but he completed all of them for 32 yards.
He also had a completed pass to Dwayne Bowe for a go-ahead touchdown that was called back because of an illegal pick set by wide receiver Dexter McCluster. The Chiefs were forced to kick a field goal and never got the ball back as Baltimore ran out the clock.
Quinn's last start, coincidentally, came at Arrowhead Stadium as a member of the Browns.
He threw for 66 yards and two interceptions in a 41-34 victory on Dec. 20, 2009. Quinn was hurt during the game and missed the rest of the season, and hadn't played in a regular-season game again until pressed into duty Sunday against Baltimore.
"It felt great to be out there, was comfortable being at home, being on the field, but right now I'm just here to support my teammates," Quinn said after Sunday's game. "Matt is our starter and I just prepare every week like I am a starter, and I prepare myself for the moment."
The former first-round draft pick has started 12 of the 15 games he's played in over the past four-plus seasons, going just 3-9 — though part of his modest success has to do with his supporting cast in Cleveland, a franchise that was going through a major rebuilding project.
The biggest criticism of him has been his consistency. During his final season as a starter, he had a two-week stretch where he threw for 99 yards and two interceptions against Baltimore, and then threw for 304 yards and four touchdowns without an interception against Denver.
"When he goes into the game, he needs to function," Crennel said. "That's how you try to build your team. That's why you have enough guys, so when a guy gets banged up, you can put another guy in who can step up to the plate and get something done."
