Britton said X-rays taken on Saturday came back negative, and he wasn't sure yet if there will be an MRI done. The injury occurred while he was trying to make an on-the-run scoop and flip with his glove on Adam Eaton's two-out bunt single.
"I've never done anything to my ankles, so I didn't really know what I was feeling. Didn't feel very good," Britton said. "Just kind of felt like I had jammed it, I guess. The best way to describe it. But Richie [Bancells, head athletic trainer] kind of took charge and said, 'That's it.'"
"There's some areas that are painful right now, but overall, it's isolated compared to last night. Last night, it was kind of everywhere. And this morning, it's in one spot, which is a good thing, from what the doctor said. Now, we kind of have an idea of what it is."
Britton doesn't have much swelling and said he's already feeling better.
"I think he'll be a pitcher shortly, hopefully," manager Buck Showalter said. "It's the left one. I kind of like that better than the right [ankle]. I'd rather have that one as opposed to the landing foot. I think he jammed the capsule a little bit as opposed to turning it. … The lack of swelling kind of reiterated what Richie thought it was, looking at the tape."
Without Britton, the Orioles will likely play matchups and won't necessarily just slot everyone back an inning and have setup man Darren O'Day in the ninth.
"I think about anybody that gives us the best chance to win," Showalter said, when asked if Dylan Bundy is an option. "All eight guys in there are in play. Not one more than the other."
