Houston running back Arian Foster went down in a heap without taking a hit.
Foster injured his right Achilles tendon late in the fourth quarter of Houston's 44-26 loss at Miami on Sunday. Texans coach Bill O'Brien said he didn't know the severity of the injury, but added "it obviously didn't look good." If Foster tore his Achilles, his season is over.
Foster was starting to run a pass pattern off pre-snap motion when he fell to the ground and grabbed his leg. He was helped off the field by teammates and training staff.
