The Chiefs rallied to beat the Bills 30-22 on Sunday, extending their winning streak to five games and improving their record to 6-5 on the season.

The win didn’t come without some setbacks, however. Linebacker Justin Houston was forced out of the game in the first half with a knee injury.

After the game, coach Andy Reid said, via Terez Paylor of the Kansas City Star, that Houston suffered a knee sprain. PFT has learned that Houston will have an MRI to determine the severity of the injury, but that the team is optimistic that Houston, who walked out of the locker room on his own power, avoided anything too serious.

The Chiefs also lost left tackle Eric Fisher during the game after he suffered what they called a head/neck injury.
