CLEVELAND -- The Indians lost two more players to the disabled list Thursday. As for the three who were already there, one is throwing, one is lifting and one is healing.

On Thursday, right-hander Fausto Carmona threw his first bullpen session since going on the DL with a left hip strain on May 24. Carmona threw nothing but fastballs and changeups in the 35-pitch session.

"It went very well," head athletic trainer Lonnie Soloff said. "If all progresses well, he'll throw a 50-pitch, all-pitch bullpen Saturday."

Assuming that goes to plan, Carmona would be ready for his first rehab start sometime next week, though Soloff said no specific date or location has been set.

Right-hander Jake Westbrook had successful Tommy John ligament replacement surgery performed on his elbow Thursday morning in Los Angeles by Dr. Lewis Yocum. Westbrook, who is expected to be out for 10-12 months, will fly back to Cleveland on Friday and began physical therapy Saturday.

Designated hitter Travis Hafner continues to strengthen his strained right shoulder and take dry swings in the indoor cages at Progressive Field. The Indians will evaluate Hafner over the weekend to determine when to send him out on a rehab assignment. The hope is that he will be ready for a rehab while the club is in Colorado and Los Angeles next week and be ready to return when the team comes home from the trip.
