Texans coach Gary Kubiak called it a "very serious" ankle injury and said Tate will undergo surgery. The report also said Tate would be placed on injured reserve, which would end his season.
Tate injured himself after a 12-yard run in the third quarter and was carted off the field for X-rays. He posted on his Facebook page Sunday afternoon that he did not break his ankle, which was the initial fear.
Tate was a second-round pick by the Texans at No. 58 overall in last spring's draft. He had a chance to be the team's top running back, competing with Steve Slaton and Arian Foster.
