Injury could force Johnson to sit

Texas sophomore tailback Cody Johnson is nursing a hamstring injury that could cause him to miss the rest of the Longhorns' spring practices.

Johnson, a bullish 5-foot-11, 255-pounder who rushed for 338 yards and a team-leading 12 rushing touchdowns last season, tweaked his left hamstring at the team's Wednesday practice.

Texas trainer Kenny Boyd said that Johnson will likely miss the rest of spring drills.

Johnson had been involved in a tight battle for the Longhorns' starting tailback position along with Vondrell McGee, Fozzy Whittaker and Tre' Newton.

After Johnson had battled weight issues for much of his freshman season, Texas coaches had been pleased with his work during the spring. He emerged as the first-string running back when the team returned to practice from spring break earlier this week.

"We've quit trying to get Cody to lose weight, we're working with body fat and we think that's the key to it," Texas coach Mack Brown said. "He looks like he's in good shape. He came back in good shape after the break. We feel like that he's doing a really good job."

The Longhorns will conclude their spring work April 5 with the Spring Jamboree Scrimmage.
