Tyson Ross won't require surgery on his injured right shoulder, but he also isn't likely to make a Major League appearance in the near future.

Ross made one start before landing on the disabled list retroactive to April 5. He underwent an MRI.

"The good news was [it's] non-surgical," Andy Green said. "We'll take a couple more weeks, re-evaluate, see where he is. Hopefully he's back on the mound quick for us."
