The Carolina Panthers have ruled out quarterback Cam Newton for their Week 5 game against the Houston Texans.

Newton, who has a foot injury, will once again be replaced in the lineup for Sunday's game at Houston by quarterback Kyle Allen.

Allen starred in Newton's absence against the Arizona Cardinals in Week 4, throwing for four touchdown passes to lead Carolina to a 38-20 road victory.

"What Cam needs right now is time and rest for his foot. We want him at 100 percent when he's ready, so there's no exact timetable for his return," coach Ron Rivera said in a statement Monday. "At this point, we're going to go forward with Kyle (Allen) as our starter."

Allen completed 19-of-26 passes for 261 yards in the victory, finishing with a 144.4 passer rating.
