San Francisco 49ers star Dre Greenlaw ejected for headbutting helmetless Seahawks rival in senseless sideline bust-up

The linebacker was tossed during the second quarter after he sparked a heated confrontation on the Seattle sideline and shockingly headbutted an opponent. Greenlaw was initially called for a personal foul for a late hit on Seahawks quarterback Sam Darnold with 6:23 left in the second quarter. However, he did not stop there. The Niners player continued to spark tensions as he found himself surrounded by Seahawks players following his pursuit of their quarterback.
