Brendan Donovan, who suffered a concussion on Aug. 22, said he’s still dealing with nausea while doing drills.

“I get on the field, and I feel like I’m going to throw up,” Donovan told MLB.com’s Daniel Kramer. “And then I take ground balls, and I have to take every other one because I’m going to throw up. So that’s kind of been the process to this point.” Donovan is still hoping to return before the end of the season, but it’s difficult to be optimistic at this point.
