GREEN BAY, Wis. -- Despite being on crutches and in a boot after Sunday's game, Jared Cook's right ankle injury is not expected to end his season.

Sources told ESPN that the Green Bay Packers tight end is expected to miss some time after this week's bye, but the team is still trying to determine whether Cook will miss only a game or multiple games.

Cook injured his right ankle in the second quarter of Sunday's 34-27 win over the Detroit Lions. He limped off the field after he dropped a deep pass and got tied up with Lions safety Rafael Bush. He was immediately taken to the locker room and did not return.

Coach Mike McCarthy said after the game that Cook was scheduled to undergo more tests on Monday.

Cook was the Packers' lone significant free-agent signing this offseason. They gave him a one-year, $2.75 million contract in hopes that he would provide Aaron Rodgers with a deep threat down the middle. In two-and-a-half games, Cook has six catches for 53 yards without a touchdown.

Cook missed part of the offseason program after underdoing foot surgery in June and missed the early portion of training camp.

The Packers don't play again until Oct. 9 against the New York Giants.
