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.

Dodgers manager Don Mattingly explains restraint on Justin Turner

Throughout the season, Dodgers manager has reiterated that he does not view Justin Turner as a player who can play six or seven times a week.

Turner is batting .288 with five homers and 17 RBIs in 35 games and has been one of the Dodgers’ more consistent hitters.

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.
