Roster spots are earned and not stolen, but through one week of training camp at the NovaCare Complex, it's the big, physical receiver, Elijah Cook, making a name for himself ahead of players with bigger expectations. The Eagles signed Cooks to a reserve/future contract following the Super Bowl.

On the first full-padded practice of training camp, the heat took over the NovaCare Complex. The Eagles moved practice up an hour due to temperatures that reached up to 96 degrees, one of the hottest days of the summer.

Eagles head coach Nick Sirianni said it's important for the team to practice in the heat, since they will need to play in it. Meanwhile, Dr. Rob Danoff shares more about the signs of heat-related illness.
