Dodgers manager Don Mattingly recounts his concussion as a player, caused by Rex Hudler

In the wake up Yasmani Grandal’s concussion sustained Friday night against the San Diego Padres, Dodgers manager Don Mattingly recounted when he sustained a concussion as a player with the New York Yankees.

It involved breaking up a double play, getting hit in the head by Rex Hudler and a funny story about Yankees trainer Steve Donohue.

Mattingly stayed in the game but admitted he had been knocked out. The new rules for a concussion by Major League Baseball are designed to protect players from concussions. Grandal is on the seven-day disabled list to give him time to recover.

Mattingly said he tries to use Turner as much as he can and said Turner’s knees prevent him from being that everyday guy, at least for now.
