The Facts: After suffering at least his fourth concussion in the past two seasons last weekend, Fiedorowicz could be forced to retire at age 26, sources told ESPN's Adam Schefter.

Diehards Line: Fiedorowicz, a 2014 third-round pick out of Iowa, was placed on injured reserve in early September because of a concussion. He returned to Houston's active roster in Week 10 but was placed on IR again last week after suffering at least his third concussion this season. Now, either by his choice or that of the Texans' doctors, Fiedorowicz might not be able to play again, sources tell Schefter. He will have to pass a team physical, and there are no assurances at this point that he can do that. If he can't, his career could be over.
