Cobb was struck in the right ear by a liner hit by Kansas City’s Eric Hosmer on June 15. He underwent the test Wednesday.
He says he hasn’t gotten the results back, but is optimistic.
Cobb had his third bullpen session since being hurt before Thursday’s game against Minnesota.
The next step is either another bullpen session or batting practice behind a protective screen.
He says he is still dealing with vertigo-like symptoms but he hopes to rejoin the rotation by August.
