Pittsburgh Steelers head coach Mike Tomlin has admitted his behaviour against the Baltimore Ravens was "embarrassing, inexcusable, illegal" and a "blunder".
The Steelers chief appeared to obstruct Ravens kick returner Jacoby Jones during the NFL game between the two sides last weekend.
Jones looked set to score as he streaked down the sidelines, but Tomlin - who was illegally stood on the field looking up at the big screen - forced Jones to break his stride and the Ravens returner was caught by a covering Steelers defender.
While Tomlin has conceded his actions were a mistake, he insisted he would "never consider doing such a thing" intentionally.
And the Steelers head coach said he would "take his medicine" regarding reports that the NFL were set to hand down a stiff punishment for his actions.
Tomlin could face a six-figure fine for the indiscretion, while some reports have even suggested the Steelers organisation could forfeit draft picks as a result.
