Carlos Rodon's debut with the New York Yankees has hit another snag.

Rodon said Friday that his back issue is "chronic," and he will have a cortisone shot next week in hopes that it speeds up the recovery process. When asked if a return in July is realistic, the Yankees' prized free agent signing deferred to the team's training staff.

"I can't put a timeline on anything," Rodon told reporters in Tampa. "I'll get this injection and I want to throw as soon as I can."
