GOODYEAR, Ariz. -- Tribe pitcher Gavin Floyd will be sidelined indefinitely after he re-injured his right elbow.

Floyd suffered a stress fracture in that same elbow last summer and missed the majority of the 2014 season. Floyd signed a one-year contract with the Indians over the winter for $4 million, with another $6 million available via incentives.

How long Floyd remains on the shelf depends on the course of action he and the training staff take. The Indians announced that the organization's medical staff is "in the process of gathering information on the best treatment option." That could include another surgery. Floyd underwent an operation late last June to stabilize the fracture in his elbow. The year before, Floyd had Tommy John surgery.

Floyd, 32, had an MRI on Sunday. He was originally slated to pitch on Sunday, but after feeling some discomfort, he played catch twice over the weekend instead. Floyd posted a 2.65 ERA in nine starts last season before the injury.

The injury could open the door for both Danny Salazar and T.J. House to occupy the final two spots in the Indians' rotation. Bruce Chen, Shaun Marcum, Zach McAllister and Josh Tomlin are also vying for a spot.
