Arizona starter Brandon Webb will now sit for at least six more weeks with a strain in his right shoulder.
However, he isn't concerned about the long-term severity of the injury.
"I came in today and I felt fine; that's what is kind of frustrating about it," Webb said. "All my exercises I did (with team trainers and Dr. Michael Lee), those were great.
"I feel as strong as I ever felt in those, so that's good. It's a muscular thing, and our trainer kind of described it as a hamstring pull or strain in your arm, which someone like Byrnsie (Eric Byrnes), it took him a while last year, so that's kind of what we're dealing with."
Webb was expected to return much sooner, but he suffered a setback in his evaluation on Friday.
