IF Jose Vallejo to have hand surgery
02/09/2010 4:41 PM ET

Astros infielder Jose Vallejo is scheduled to undergo surgery on Wednesday to repair severed tendons in the fourth and fifth fingers of his right hand and is expected to miss most of the 2010 season, General Manager Ed Wade announced today.

The surgery will be performed by Dr. Thomas Melhoff at Texas Orthopedic Hospital in Houston. Vallejo severed the tendons while preparing dinner at his home in the Dominican Republic during the Christmas holidays. The injuries occurred when his hand slid over the knife blade he was using to cut meat.

"Jose's injury is really unfortunate," Wade said. "He did a nice job after we acquired him and looked really good in the Arizona Fall League. Hopefully, the surgery and rehab will go well, and he'll be back on the field at some point."

Vallejo, 23, was acquired by Houston from Texas on August 20, 2009, as one of the players to be named later in the Ivan Rodriguez trade.

LYON HAS SMALL CYST DRAINED

Wade also announced today that Astros right-handed pitcher Brandon Lyon had a small cyst in his right shoulder drained.

The cyst, which was drained at the Methodist Hospital in Houston, was pressing on a nerve and causing temporary weakness in Lyon's shoulder. Lyon was examined after the procedure by Astros team physician Dr. David Lintner, who believes that draining the cyst will alleviate the weakness in the shoulder. Lyon has been throwing without discomfort since the cyst was drained two weeks ago.

"Brandon was experiencing some weakness and discomfort in his shoulder, and we brought him in a couple of weeks ago to be seen," Wade said. "At the time of his pre-signing physical, his right shoulder MRI showed a very small cyst, and when the MRI was repeated recently, it showed that the cyst had enlarged and was pressing on some nerves.

"Since having it drained, Brandon reports no problems, but he will be making up for a little bit of lost time when he gets to Kissimmee."

Lyon is expected to begin Spring Training workouts with the rest of the Astros pitchers and catchers on February 20, but may be behind in this throwing program by approximately 10 days.

Lyon, who was signed by the Astros as a free agent in December, was 6-5 in 65 relief appearances for Detroit in 2009 with a 2.86 ERA (25ER/78.2IP) and a .205 opponents batting average (56 hits allowed in 78.2 innings).
