Lions rookie quarterback Matthew Stafford has undergone successful surgery on his right knee. Stafford had what the Lions called minor surgery on Tuesday. He was placed on injured reserve last week. Stafford completed 201 of 377 passes for 2,267 yards with 13 touchdowns and 20 interceptions this season.

The Lions have signed veteran quarterback Patrick Ramsey. Ramsey will take the roster spot of rookie Matthew Stafford, who was placed on the injured reserve by Detroit. He was with the Titans until October when they released him.

The Lions have placed rookie quarterback Matthew Stafford on the injured reserve with a knee injury. Detroit coach Jim Schwartz says the No. 1 overall pick in the 2009 draft will undergo surgery after the season. "We anticipate a minor surgery just to clean out some irritants and debris," Schwartz said. "Since he's had [the injury], he's had on-and-off swelling. It's been stuff he's been able to play through, but it's also something we knew we needed to address after the season." Stafford threw for 2,267 yards, 13 touchdowns and 20 interceptions in 10 games.

Lions rookie defensive back Louis Delmas told reporters on Sunday that he doesn't pay attention to the team's record. Detroit lost 31-24 to Arizona in Week 15, falling to 2-12 on the season. "I don't really pay attention to (our) record," Delmas said, when asked how much the losing is bothering him. "But if I did, I'd probably kill myself. I just pay attention to the game. Once you're losing, you aren't going to see any smile on this face. This loss is very tough on us, not only myself, but the team." Delmas returned an interception 100 yards for a touchdown in Detroit's loss to Arizona.

The Lions pulled a struggling Daunte Culpepper in favor of Drew Stanton on Sunday against the Cardinals. Detroit made the change at halftime and Stanton helped lead the Lions back into the game, which they eventually lost 31-24 at Ford Field. Culpepper was 6-for-12 with 64 yards and an interception when he was replaced. Stanton finished 10-for-19 with 72 yards and a pick of his own.

Lions running back Kevin Smith may not be ready for the start of the 2010 season after suffering a knee injury this past weekend. Tom Kowalski of MLive.com writes that Smith's injury could alter Detroit's draft strategy. He eventually will return from knee surgery, but he probably won't be 100 percent healthy until the 2011 season. Smith rushed for 747 yards and four touchdowns on 217 attempts.

Lions running back Kevin Smith likely suffered a season-ending ACL tear in the team's loss to the Titans on Sunday. An MRI exam on Monday will gauge the extent of the damage, a league source told Pro Football Talk. Smith had 678 rushing yards and four touchdowns heading into Week 14.

Bengals wide receiver Chad Ochocinco has gotten into a war of words with Lions cornerback Louis Delmas. Ochocinco called out Detroit's players prior to Sunday's game between the Bengals and Lions, and Delmas told the media that he expected to jaw with the receiver. "Come on," Ochocinco said. "Tell him to sit down. Don't do that. Don't do that. Because he's gonna end up having a bad day. You're not gonna beat me at my game."
