Jabari Parker had himself a dunk-tacular game against the Dallas Mavericks on Saturday night, but none more eye-catching than this two-handed jam that caused him to hit his head on the rim.

The third-year forward blew past Quincy Acy and went airborne full speed a-head (get it?) and couldn't stop his momentum after dunking the ball, dinging his forehead on the front of the rim. Take a look.

The Milwaukee Bucks Twitter account showed Parker icing his head on the bench, but he would come back cool-headed to jam some more.

The 6-foot-8 forward had himself a dunkfest in his 24 minutes of playing time, none sweeter than this spin move in transition to lead to the one-handed throwdown over Wesley Matthews, who was quick to get out of the way.
