Jordy Nelson’s season is likely over, and the same looks to be true for Davante Adams.

The Green Bay Packers’ starting receivers are unlikely to play in Sunday’s regular-season finale at Detroit, leaving both of their futures in doubt.

Nelson suffered a shoulder injury in Saturday’s shutout loss to Minnesota, and coach Mike McCarthy said the 32-year-old is a long shot to play against the Lions. Adams remained in the concussion protocol on Wednesday and hasn’t played since he suffered his second head injury of the season on Dec. 17 at Carolina.

“It’ll be tough for him to make this week,” McCarthy said Wednesday.

Nelson’s production has slipped this season, and even the return of quarterback Aaron Rodgers from his broken collarbone for the Panthers game didn’t jump-start the receiver. Nelson was leading the league with six touchdown receptions when Rodgers got hurt in Week 6 but hasn’t caught one since. He has 53 catches (his fewest since 2010) for 482 yards (his fewest since 2009). Nelson has one year left on his contract and is scheduled to make $10.25 million in salary and bonuses next season.
