Nestor Cortes is the latest member of the Yankees squad to probably head to the IL list, as he has been suffering from a shoulder issue.
The extent of the injury will only be determined after Nestor Cortes undergoes an MRI in New York on Monday. Regarding his situation, he stated:
"I'm not really concerned. It's just a lot of soreness. I haven't been able to bounce back like I want to between starts. Hopefully, everything comes back clean [Monday] in the MRI and we can just get ahead of it and get better." (via Nypost.com)

He further stated that he has not experienced anything like this in the past and hopes it's more of a shoulder inflammation. However, he's also waiting for the MRI images to fully understand what happened to him.
New York Yankees manager Aaron Boone, however, sounded optimistic regarding Cortes' injury. He stated:
"That’s our sense now, but again, we haven’t had tests. That’s the trainers’ sense, that this is probably not [surgery]. But then again, we’re speculating there." (via MLB.com)
Shoulder injuries take time to heal, depending on their severity. In the case of mild injuries, it takes about four to six weeks to heal completely. However, serious injuries may take more time.
In Nestor Cortes' situation, his return to the team will only depend after he gets the MRI done on Monday. It seems that it might result in him missing out on more than one or two starts.
