Detroit Lions defensive tackle Jason Jones is out for the year with a left knee injury.
Jones ruptured his left patella tendon in the second quarter of the Lions' 27-20 win over the Washington Redskins on Sunday.
Jones was carted off after a pass play with 5:55 remaining in the first half.
Jones signed with the Lions as a free agent in March. The 2008 second-round draft pick spent four years with the Tennessee Titans and then played last year with the Seattle Seahawks.
