Pryor (quadriceps) was on the field participating in Thursday's practice, Ashley Landis of hjnews.com reports.
Pryor missed part of the Texans' OTAs in early June due to a quadriceps injury. The tight end has since recovered from the issue and is a full participant in training camp as he attempts to move up the depth chart and survive cutdown day. The 23-year-old out of Iowa has yet to play in an NFL game.
