Gil was placed on Triple-A Scranton/Wilkes-Barre's 7-day IL on Friday due to right shoulder inflammation, Erik Boland of Newsday reports.
Gil has been with the Triple-A club for less than two weeks after he was optioned April 26. He didn't make any appearances with Scranton/Wilkes-Barre before landing on the IL, but Yankees manager Aaron Boone indicated that the shoulder inflammation is a new concern rather than one that contributed to Gil's poor performance while he was with the big-league club. Boone added that Gil won't throw for at least three weeks, so the right-hander is looking at an extended absence from game action.
