Hoyer suffered a concussion Sunday night against the Patriots, NFL.com reports.
Hoyer was forced out of Sunday's game during the fourth quarter, which resulted in backup T.J. Yates finishing the game at quarterback for the Texans. Since it's now Hoyer's second concussion in the past month, the veteran's status for Week 15 against the Colts is highly questionable. As a result, Yates is expected to be prepared to start Sunday's divisional clash.
