Marc Topkin of the Tampa Bay Times writes that right shoulder surgery for Jeff Niemann "remains likely." Niemann is being re-evaluated Monday evening, and an announcement might not come until Tuesday. However, it's looking like surgery -- likely of the season-ending variety -- is probable. It's a blow to the depth of the Rays' rotation, but they have Chris Archer and Jake Odorizzi at Triple-A if Roberto Hernandez falters.
