Brandon Pettigrew's season, and perhaps his Detroit Lions career, ended with a Christmas Day trip to injured reserve.

Pettigrew, who will be an unrestricted free agent this offseason, suffered an ankle injury Dec. 16 against Baltimore and hadn't practiced since.

Detroit will have to add at least one tight end for Sunday's season finale against Minnesota, with Pettigrew out and Dorin Dickerson coming off a concussion. Joseph Fauria is the only healthy active player at the position.

The Lions worked out some tight ends this week, and also have Matt Veldman on their practice squad.

Pettigrew started slowly this year, including getting de-emphasized in the game plan for a Week 3 win against Washington, but flourished after that. He was called upon to do a little bit of everything, as the only blocking tight end on the roster, and managed to still catch 41 passes for 416 yards and two touchdowns.
