RB continued to play through pain
Coach Gregg Williams wouldn't provide the full extent of the injury, and didn't rule Henry out of next week's game against Indianapolis.
"We'll take it day by day," Williams said.
Henry was wearing a protective boot Monday but was walking without a limp, and his condition will be monitored throughout the week.
It was a remarkable performance for Henry, who finished with 23 carries for 149 yards rushing, with 10 of those carries and 34 yards coming after cracking his fibula.
Henry was injured after a 3-yard run up the middle inside the Texans' 10. It appeared linebacker Jay Foreman rolled up on the back of Henry's leg when he was down.
Henry had to be helped off the field, and was carted off for tests. He returned for the start of the third quarter.
Henry played through pain before, missing only one game earlier this season after he tore cartilage in his rib in Buffalo's 17-7 loss at Miami on Sept. 21.
Henry wasn't available for comment.
The Bills also lost safety Izell Reese, who sustained a concussion in the fourth quarter.
