Hunter sustained the injury when he was hit in the stomach by Texans safety Danieal Manning.
"It was a surprise to us that he was taken to the hospital," Nate Washington said. "This is a situation where football goes out the window. He has internal bleeding. … Any time a guy is spitting up blood you have to be concerned. This is bigger than football. I just hope that everything is all right. ... Justin is like a brother to me, and I want to make sure he is OK."
Hunter had one catch for 18 yards before he left Sunday's game. In 11 games this season, Hunter has 27 receptions for 480 yards.
