Triston Casas: Everything you need to know

Casas (knee) was diagnosed with an abdominal strain Tuesday, Tim Healey of The Boston Globe reports. Casas began the regular season on the injured list to finish up his recovery from patellar tendon surgery but began to have problems with his left side after he resumed a swinging progression. Now that he's been confirmed to be dealing with an abdominal strain, the 26-year-old will be shut down from all activity until he begins to feel better. The Red Sox will then begin to build him up in a similar fashion to spring training, at which point a clearer timeline for his return to play could emerge.

Casas (knee) will be "out a while" with what is now being described as a likely oblique issue, Chris Cotillo of MassLive.com reports. Casas opened the season the 10-day injured list while continuing to rehab from left knee surgery. He had been swinging a bat but was shut down in early April with what was initially deemed a left intercostal strain. Casas tried to resume swinging less than a week later, but that didn't go well, and he was consequently sent in for an MRI. While Boston is still waiting for the results of that imaging, manager Alex Cora said Saturday that the organization is now treating the issue "like an oblique, rib injury." Cora added, "He's going to be out for a while but we're still waiting for the news from the doctor."

Red Sox manager Alex Cora said that Casas (knee) is headed for imaging on his ribs after he tried to swing a bat Monday and "it didn't go well," Gabrielle Starr of the Boston Herald reports. Casas -- who initially went on the injured list as he recovers from last May's knee surgery -- was recently diagnosed with a left intercostal strain. More will be known about a possible timetable for Casas after his imaging results are in, but he won't be back anytime soon even if he gets a favorable result.
