From the Associated Press:

ALLEN PARK, Mich. -- The Detroit Lions say 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 after a physical exam revealed he wouldn't be ready to play in Sunday's season finale against Chicago.

Stafford completed 201 of 377 passes for 2,267 yards with 13 touchdowns and 20 interceptions this season. He either threw or ran for a touchdown in all 10 of his starts, including one pass in Detroit's 19-14 win over Washington in Week 3.
