Lions quarterback Matthew Stafford could be done for the season, according to a report from MLive.com.

This has not been confirmed by the team.

Stafford injured his right/throwing shoulder late in Sunday’s overtime loss to the Jets.

According to the report it is a grade 3 separation which means there’s tearing of the ligaments and capsule surrounding the joint and it could require surgery.

This is the same shoulder that Stafford injured in the season opener at Chicago.

Coach Jim Schwartz said on Monday that from his knowledge this was not an aggravation of that injury, it was a new injury.

Schwartz also said on Monday that “from my information there’s no surgical option at this point.’’

In a radio interview on Monday night, Stafford would not spill much information. He said he did hurt the shoulder earlier in the game, but not seriously enough to knock him out of action.

Stafford said he didn’t think he would play on Sunday.

This is new and frustrating territory for him. He said he never missed a game in high school or college because of an injury.

This is his fourth significant injury in his first two seasons in Detroit. Last season he had a kneecap separation and a left shoulder separation. He had knee surgery before the season was over.

This year it’s been two separations of his right shoulder.

In his three starts this season Stafford has thrown six touchdown passes and just one interception.

Shaun Hill, who started five games in his absence, is recovering from a broken left forearm, his non-throwing arm.

Schwartz said Hill “could potentially be ready” to play on Sunday at Buffalo.

If not, Drew Stanton will get the start.
