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.
