Serious Medical Condition: O'Nora Tears Intestine, West In

Brian O'Nora's serious medical condition is an intestinal tear; accordingly, O'Nora is out indefinitely. Last Friday, O'Nora hastily exited the Phillies-Mets game in the first inning. Initially reported by beat reporters as "O'Nora swallowed his chew," MLB PR quickly diffused the charges, noting that O'Nora not only left the game due to a "serious medical condition," but that O'Nora does not even use "any tobacco products."

O'Nora's abrupt absence caused Fieldin Culbreth's crew of Adrian Johnson and Bill Welke to be without a fourth umpire Friday. On Tuesday, "Country" Joe West, fresh off his Triple-A MiLB rehab assignment that took him to Oklahoma City, joined Culbreth and company as the third base umpire for the 4/30/13 White Sox vs. Rangers game in Arlington.

MLB indicated there is no timetable for O'Nora's return.

O'Nora and West both were selected to work the 2012 World Series; O'Nora had home plate for the Giants' clincher.
