He must decide whether to go through a rehabilitation process or undergo Tommy John surgery, which would sideline him for about a year.
"It's disappointing," Edgin said, according to the Associated Press. "Actually, really disappointing. We're going to have a great year this year, whether it's with me or without me."
One option for Edgin is to rehab the elbow for two-to-three weeks and later decide to undergo surgery if the elbow does not respond.
"A decision is expected in the next day or two," Mets general manager Sandy Alderson said, according to the AP. "It's not black or white. There's a certain amount of gray area here that requires some judgment on the physicians' part, as well as Josh deciding exactly how he wants to approach it."
Edgin is expected to begin the season on the disabled list.
