Diontae Johnson's on-field frustration 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 Adam Schefter of ESPN.

Order eventually was restored in the 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.

Pittsburgh's on- and off-field performance in the 13-10 loss was a clear tipping point, leading the Steelers to make their first in-season coaching change since 1941. After another inept offensive performance and the outburst from Johnson, it became apparent that the Steelers needed to make a move.

Johnson, who had just two catches against the Browns, was visibly upset on the sideline during the game, engaging in an animated conversation with Steelers head coach Mike Tomlin.

But the heated words didn't stop there.

One source told ESPN that Johnson, the Steelers' second-leading receiver, continued "chirping" at the coaches all the way into the locker room, where Fitzpatrick -- a three-time first-team All-Pro -- began arguing with Johnson. The words between Johnson and Fitzpatrick became "heated," according to another source, before Heyward and Watt intervened and prevented the situation from getting worse.

Heyward and Watt calmed everyone down before they and Tomlin addressed the situation. Sources around the team believe the Steelers have been able to move on, and the incident has not carried over into the team's preparation for Sunday's game against the Bengals.

But the argument also is an example of the effect that the Steelers' struggling offense has had on the entire team, as tempers flared and emotions took over, even getting the better of some of Pittsburgh's top players.
