There was drama surrounding Stefon Diggs and the Buffalo Bills last week.

Diggs was not in attendance last Tuesday when camp opened up, and Sean McDermott said he was "very concerned" about the situation.

After that first practice session, Josh Allen told reporters that Diggs' issues were "not football-related." The next day, Diggs returned to the facilities and was on the practice field.

According to a report, Diggs' frustration is due to his role in the offense and his voice in the team's play-calling.

Diggs caught 108 passes for 1,429 yards and a career-high 11 touchdowns in 16 games played last season.

However, after being upset by the Cincinnati Bengals in the divisional round, The Athletic reported that Diggs sprinted out of the locker room with all of his things before some of Buffalo's coaching staff even made it down to the tunnel that leads to the locker room.

He was seen "exchanging some words" with Allen on the sideline during the loss, and later took to Twitter to explain that he just wasn't OK with losing.
