As first reported by ESPN's Adam Schefter, the Lions have placed kicker Jason Hanson on injured reserve, ending his 2010 season. Hanson had originally hoped to return on Thanksgiving, but apparently his knee injury is more severe than originally anticipated.
Hanson suffered the knee injury on Nov. 7 against the Jets. He had his knee/leg rolled on by a diving Jets player on a field goal. The injury led to the Lions' drive continuing and a touchdown being scored. (It also caused Ndamukong Suh to attempt an extra point.)
With Hanson done for the season, it looks as though Dave Rayner will be the Lions' kicker for the final five games. In the three games he's appeared in so far, Rayner has made four of six field goals and five of five extra points.
UPDATE: The Lions filled Hanson's roster spot with cornerback Tye Hill. Hill was drafted by the Rams in the first round back in 2006. He was traded to Atlanta a year ago and spent this past offseason with the Titans. He has been a free agent since being waived during the final round of roster cuts.
