Diontae Johnson's on-field frustration last Sunday in Cleveland continued after the game in the Pittsburgh Steelers' locker room, where he got into a heated argument with teammate Minkah Fitzpatrick before Cameron Heyward and T.J. Watt broke up the altercation and delivered a message that the team needed to stick together, league sources told ESPN.

Order eventually was restored in Pittsburgh's locker room, but the argument between two of the team's star players left a mark going forward on the Steelers, who fired offensive coordinator Matt Canada two days later.
