Brian Wolfe started a game against the Rakuten Eagles at Rakuten Seimei on April 15. He was pulled from the game after he developed some tingling near his right elbow (he left after he threw two pitches to the eleventh batter of the first inning). The Seibu Lions will make a decision on Wolfe after he gets checked out at the hospital.
[UPDATE 4/18 @ 3:38pm]
Wolfe was examined at a hospital in Tokyo on April 16. Doctors found that the tingling was caused by an ulnar nerve coming into contact with bone. He was treated with an injection. He was able to throw about thirty pitches in the bullpen on April 17.
