Here's some quotes:
“I didn’t know how it was going to be until I got out there,” he said. “I thought it was going to be okay. It felt loose yesterday but not real explosive, but I had a lot of work done on it.” -Morrow
“We don’t think it’s much of an issue,” Gibbons said. “The doctors don’t think it’s much of an issue. It’s one of those things where we held him out as a precaution.” -Gibbons
There's also a video on the site where Morrow says it's not near the ligament just to put that to rest.
I'm still doubtful he makes his next start but at least we're not looking at another TJS.
