They could get at least two of those players back next weekend against the Atlanta Falcons.
Texans coach Bill O'Brien said running back Arian Foster and receiver Andre Johnson have "a shot" to return for the team's second preseason game. Both have soft tissue injuries, Foster suffered injury on July 27 and Johnson on July 28. Foster returned for one day of practice since then, which means both have missed the same number of days while healing.
O'Brien said Cushing might return to practice this week, but would "probably" not play in the game. That would be great news for the Texans. Right now Cushing is on the Texans' physically unable to perform list. He suffered a broken leg and torn LCL last October, an injury that finished his season.
