ST. LOUIS -- Cleveland Browns linebacker D'Qwell Jackson, the team's leading tackler, left Sunday's game against the St. Louis Rams with an ankle injury in the first quarter.
Jackson's backup, Kris Griffin, was carted off with an Achilles tendon injury. The team said both were questionable to return.
Jackson, a second-round pick in 2006, entered the game with 57 tackles. Last year he finished second on the team with 115 tackles.
