Floyd was ruled out indefinitely last week after re-injuring a stress fracture in his elbow that limited him to nine starts last season. The surgery will seek to repair the re-fractured olecranon bone in Floyd's right elbow.
"He's certainly out for the foreseeable future," Indians manager Terry Francona told reporters. "More important than talking in March about him pitching in August or September, is our getting him healthy so he can proceed with his career. As he starts to rehab and do all that stuff, some of those things get more clear.
"I think the safe presumption is he's going to miss a good portion, if not the whole year."
Floyd signed a one-year, $4 million deal with the Indians this winter. He spent last season with the Atlanta Braves, but sustained the initial stress fracture on June 19. He had season-ending surgery six days later.
Over 208 games (196 starts), Floyd is 72-72 with a 4.40 ERA, 948 strikeouts and 403 walks.
