Mike Tomlin denis intentionally positioning himself in the way of Jacoby Jones in order to stop him from scoring a touch down.
With the Baltimore Ravens leading 13-7 in the third quarter in their Thanksgiving tie against the Pittsburg Steelers, Jones broke in to a clear run to the end zone but was tackled by Cortez Allen.
But during the run, Jones had to break his stride to avoid a collision with Tomlin, who was standing on the edge of the field.
The incident caused a plethora of abuse come Tomlin's way via social websites like Twitter and analysts are asking for the book to be thrown at the coach.
Tomlin has, however, come out in defence of his actions and says there should be little doubt over whether it was an accident or not.
He said to reporters: "If anybody thinks I or anybody else would do this on purpose they are crazy."
He also told his players that he didn't need them to defend him.
"I was advised that he didn't need any help in this situation and I shouldn't say much," safety Ryan Clark told the Pittsburgh Post-Gazette.
"He didn't advise us not to speak, but coach 'T' said he didn't need any help," Clark continued. "He was like, he understands the situation, he understands the process that has to happen. He was like, 'So I don't need you guys speaking up for me and trying to defend me.' He'll be fine."
A ruling from the NFL is expected to arrive this week and it is expected the Steelers will face a hefty fine.
