Washington Redskins Coach Mike Shanahan said Monday that Kyle Shanahan, his son and the team’s offensive coordinator, wasn’t the only member of the coaching staff upset at replacement officials at the end of Sunday’s loss to the Cincinnati Bengals.

“I’m not sure I was very cool under that situation,” Mike Shanahan said. “I was very, very strong with my words to the official letting him know that it wasn’t the end of the game. Now, is that cooler heads prevailing or is it trying to get one more play and explain what the rules are in the National Football League?… I was very upset at that time as well.”

The NFL is reviewing Sunday’s incident in which Kyle Shanahan was called for an unsportsmanlike conduct penalty in the game’s final seconds and then followed the officials off the field and, according to witnesses, continued to berate at least one of them. He could be fined by the league.

“I think we’ll let the powers that be take a look at what transpired on both sides and let them make the decision,” Mike Shanahan said at his news conference Monday.

Shanahan took exception to being asked by a reporter Monday whether Kyle Shanahan set a poor example for his players when the team declined to make him available for interviews. Kyle Shanahan issued a written statement through the team Monday and is scheduled to speak to reporters Thursday under the club’s usual weekly media schedule.

Shanahan told a reporter he was “really disappointed you’d even ask a question like that.”

He also said: “We’ve got a process that we work through and that’s our process…. If you want to ask a question, you can ask me. Kyle has already sent out a statement this morning, just like I would have. He wanted to talk to you guys and I said we’re going to keep the same process going.”

A week earlier, Redskins wide receiver Josh Morgan spoke to reporters following the team’s loss in St. Louis, in which he had a costly unsportsmanlike conduct penalty late in the game.

When asked if he was disappointed in Kyle Shanahan’s handling of the situation Sunday, Mike Shanahan said: “I tried to explain to you that the official told me that the game was over. We knew the game shouldn’t be over. They had half their football team on the field. What I was trying to do was get a personal foul, talking to the official because he had told me the game was over. I said the game was not over and I think we should have a 15-yard penalty [on the Bengals]. But that wasn’t the difference in winning and losing the game. Those things do occur. You would like cooler heads [to] prevail. That’s what I expect.”
