Jets TE Keller downgraded to out vs. Jaguars

FLORHAM PARK, N.J. (AP) Jets tight end Dustin Keller will miss New York's game at Jacksonville on Sunday because of a sprained left ankle.

Keller was listed as doubtful Friday after injuring his ankle last Sunday in the Jets' 7-6 win over the Arizona Cardinals. He is second on the team with 28 receptions despite missing four games earlier this season with a hamstring injury. Keller, who sat out practice all week, will likely be replaced in the starting lineup by backup Jeff Cumberland, who has 21 catches this season.

The Jets will also be without backup defensive tackle Damon Harrison, who turned an ankle during practice Thursday.

Backup quarterback Tim Tebow, recovering from two broken ribs, was expected to be a game-time decision.
