CHICAGO -- Chicago White Sox outfielder Aaron Rowand was scheduled for surgery Wednesday after being injured in an off-road dirt bike accident.

Rowand broke two ribs and the his left shoulder blade. He also bruised his left shoulder in the accident earlier this month.

Rowand said he was riding trails near Las Vegas with his brother-in-law and was traveling 20 mph before hitting a "hump.'' That sent him flying headfirst over the handle bars, and Rowand tumbled down a 25-foot embankment.

"My dirt bike days are over,'' Rowand told the Daily Herald of Arlington Heights. "It's going to be sold.''

Rowand, 25, is expected to be ready for spring training. The team will re-evaluate his status following the operation.

"I feel pretty good about being back in time, as long as therapy goes well,'' Rowand said. "There's no reason to believe I won't be 100 percent. At first, I thought it was a dislocated shoulder.''

He hit .258 (78-for-302) with seven homers and 29 RBIs in 126 games for the White Sox this year after taking over as the starting center fielder in late July, when Kenny Lofton was traded to San Francisco.

If Rowand isn't ready, Joe Borchard or Willie Harris could move into center field. But Rowand said he plans on keeping his job.

"I don't think (this) will set me back, baseball-wise,'' Rowand said. "I plan on doing one-handed drills two or three weeks after surgery.''
