Kyle Shanahan flips out on ref, goes nuts on sideline (VIDEO)

49ers new head coach Kyle Shanahan was none too pleased about the officiating in Sunday’s game against the Panthers, and he made sure to make that known.

At one point in the game, Shanahan tried to call for a timeout on fourth-and-one, but the officials didn’t acknowledge it, and the 49ers were hit with a delay of game penalty. Instead of attempting to convert for a first down, they were stuck settling for a field goal (their only points of the game).

And Shanny Jr. was not happy about it.
