After suffering at least his fourth concussion in the past two seasons last weekend, Houston Texans tight end C.J. Fiedorowicz could be forced to retire at age 26, sources told ESPN.
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, because of either his choice or that of Texans doctors, Fiedorowicz might not be able to play again, sources said.
