Dallas players Matt Hedges and Kellyn Acosta knocked heads during a match against New York City FC last weekend, a collision so intense that Hedges required six stiches at halftime and had to change his jersey because of the blood.
Yet some viewers questioned whether either player was sufficiently checked for a concussion.
"I didn't know I was bleeding until everyone started saying it was," Hedges told reporters after the game. "They bandaged it up so I could go back in and then they stitched it up at halftime. ... I love to play and I don't really care if I am hurt or whatever, I just want to be out there.
