Mark Reynolds took a fastball from Nationals relief pitcher Collin Balester off the helmet in the bottom of the sixth inning of the D-backs’ game Tuesday.

He got up on his own after being on the ground for about a minute, but was removed from the game.

Today is Reynolds’ 27th birthday, which was notable when he homered to give the D-backs a 4-1 lead in the fourth.

We definitely hope Reynolds is OK. Will post an update as soon as we have word from the team medical staff.

**Update**

Reynolds is back in the dugout, and seems OK (with the exception of an ugly gash on the left side of his head). The initial neurological exam was fine, but he’ll be reevaluated further later tonight.
