LB Jordan Zumwalt practiced for the first time since leaving practice early three days ago because of heat exhaustion. He returned today and left about 45 minutes into practice. The culprit is heat related. Seems like once you’re hit hard with heat exhaustion it’s hard to bounce back from it. WR Javon Williams left for the same reason and both were carted off together, heads hanging low, pads off and wet towels around their neck. LB Anthony Barr had a huge cast on his left arm for a broken knuckle on his left pinky. A significant upgrade from the smaller cast a day earlier. RB Darius Bell had a bit of a quad issue early in practice but seemed to be fine after a short session with trainers. WR Ricky Marvray ditched the red jersey and donned a blue jersey for the first time in fall camp, though he saw no real contact in team drills.
