Posey suffered the injury in the final moments of the game, according to the newspaper. It soured a strong performance for the rookie out of Ohio State, who had three catches for 46 yards and a touchdown in the loss.
The scoring catch -- an acrobatic grab that was overturned by replay after he originally was ruled out of bounds -- was the first of Posey's career. It cut the Texans' deficit to 38-20 with 11:35 remaining in the fourth quarter.
Posey finished the regular season with six catches for 87 yards.
There was no immediate timetable for his recovery.
