Astros right-handed pitcher Collin McHugh will not throw for a period of six weeks due to posterior impingement of his right elbow, General Manager Jeff Luhnow announced today.
McHugh, who began this season on the 10-day disabled list due to tendinitis in his right shoulder, left his first rehab start with Triple A Fresno on Thursday night after one inning due to discomfort in his elbow. He was evaluated by the Astros team physicians in Houston on Friday and diagnosed with posterior impingement of his elbow. An MRI revealed that the ulnar collateral ligament in his elbow was normal.
