Running back Joe Mixon has been placed on the non-football injury list. The team will also be without Dameon Pierce and J.J. Taylor in the backfield to start camp as both of them have landed on the physically unable to perform list.

This move comes after Aaron Wilson of KPRC 2 Houston reported Mixon was sidelined in the spring because of an ankle injury. While he is on the non-football injury list to start training camp, Wilson noted his outlook was generally positive.

HOUSTON -- Houston Texans running back Joe Mixon is starting training camp on the non-football injury list. Mixon, a Pro Bowler last season in his first year with the Texans, didn't practice during OTAs and minicamp because of an ankle injury.
