Potts to undergo surgery on hand

Texas Tech senior quarterback Taylor Potts will have surgery on his throwing hand and miss eight weeks, a school official told ESPN.com on Monday.

Potts suffered a deep laceration to the webbing between his right index and middle finger when he hit a teammate's helmet on the followthrough of a pass late in practice on Wednesday. He received six stitches, but the damage was worse than originally believed, and the surgery will fix ligament damage to his hand, keeping him out for the remainder of the spring.

Tuberville previously said he hoped to have Potts throw next week, presumably when the stitches were removed. Surgery now removes that option.

Senior quarterback Steven Sheffield, expected to compete with Potts for the starting quarterback job, underwent surgery after breaking his left foot in practice on Monday. Sheffield stepped on a teammate's foot and will be out eight to 10 weeks.

In their place, sophomore Seth Doege and redshirt freshman Jacob Karam are splitting first-team snaps evenly for the remainder of spring practice.

Last season, Potts threw for 3,440 yards and 22 touchdowns.
