7 days. Yeah, if you get hit in the head and taken out of the game you have to go on the 7 day IL for concussions.
Also, wtf is Abreu swinging at bullshit for. Kennedy didn't throw a fucking strike and Abreu still Kd.
Given it is a 10 Day IL, I think that Gio's probably going to get a little break. I'd imagine Covey is going to get the callup to be the long man, with Banuelos sliding into the rotation.
