Orioles manager Buck Showalter said Wieters will fly to Pensacola, Florida, for the exam and will rejoin the team for the game Wednesday against the Tampa Bay Rays.
Wieters, who had an MRI on the elbow earlier in the week, went 2-for-5 as the designated hitter in Tuesday night's 5-3 win over the Rays.
Wieters leads all American League catchers in batting average, home runs and slugging percentage. He also has 18 RBI and a .374 on-base percentage.
"He's been getting it treated for a while," Showalter said, via the Baltimore Sun. "We just want to make sure we know what we're dealing with. He'll be back for the game. We got an MRI (on Monday) and we just want to follow up. Hopefully he's catching for us (Wednesday)."SI.COM STAFF: MLB Power Rankings: Athletics in first, but Marlins are rolling
