Each day of training camp, we’ll check in on Patriots wide receiver Stefon Diggs, who is recovering from an ACL tear.

The Atlanta Falcons added more offensive firepower over the weekend, officially signing wide receiver DJ Chark Jr. to their 90-man training camp roster on Saturday morning. Chark is expected to help fill in for Darnell Mooney, who will be out for a few weeks due to a shoulder injury.

Here are the most important things to know from the first three practices:

Check out this video of DB Bryan Cook making an impressive one-handed interception during a practice session at Chiefs Training Camp this week.

Fans filled the sets of grandstands around the Lions’ practice fields, cheering on the likes of rookie running back Kye Robichaux after he trucked through a defender during a drill and chanted for linebacker Alex Anzalone, who was practicing for the first time during camp.

OK, so the first week of training camp was kind of a dud. Leaguewide, the first four practices were quick and pad-less, as mandated by NFL rules. The league’s medical advisers determined that a slower ramp-up to full contact in training camp will lead to fewer groin and hamstring pulls.

Buffalo Bills Star running back James Cook reported to training camp at St. John Fisher University amid contract negotiations with the team. Cook had a dominant 2024 season, where he put up 1,022 rushing yards and 16 touchdowns.

O’Connell leans heavily on input from Tyler Williams, the team’s vice president of player health and performance. They map out workloads for every practice down to how many reps in each period. Practices typically have eight to 10 periods split among individual position drills and full-team sessions.

Eagles first-round pick Jihaad Campbell wasn't expected to practice until August following offseason shoulder surgery to repair a torn labrum. Not only is Campbell participating in training camp, but he's also getting first-team reps in just the third session of the summer.
