Sheffield has surgery on left foot

LUBBOCK, Texas -- One of the two senior quarterbacks vying for the starting spot in Tommy Tuberville's first season at Texas Tech will miss at least eight weeks after surgery on his left foot.

Tuberville says Steven Sheffield will be out eight to 10 weeks after surgery Wednesday to repair the same bone injured in October at Nebraska. He re-injured it at the end of practice Monday.

Sheffield and Taylor Potts, who started for Tech at the beginning of last season, are competing to be the Red Raiders' starter next season. Tuberville says Potts will be out for a week with stitches between his index finger and middle finger after hitting it on a helmet while throwing.

Sheffield threw for 1,219 yards and 14 touchdowns in six games in last season. Potts had 3,440 yards and 22 touchdowns in 12 games last season.
