Regarding defensive end Aidan Hutchinson’s knee injury, Lions coach Dan Campbell said after Sunday’s win over the Patriots, “We’ll know more when we get back in the States.”

Apparently, they already know plenty.

Multiple reports indicate that the Lions have already determined that Hutchinson suffered a “significant” knee injury.

There are some inconsistencies in the reporting. Tom Pelissero of Netflix said it’s definite — and that it’s a season-ending injury. NFL Network reports that Hutchinson is “feared” to have suffered a significant knee injury, which will sideline him “for the foreseeable future.”

The worst outcome, and the most definite season-ender, would be a torn ACL.

Hutchinson suffered the non-contact knee injury while celebrating a sack. It’s possible that, if the ACL is now fully torn, it was already partially torn, unbeknownst to Hutchinson or the Lions.

Regardless, Hutchinson apparently will be out for some period of time, if not for the rest of the season. The Lions host the Buccaneers next Sunday before the Bears visit on Thanksgiving.
