Peterson to miss spring practice following shoulder surgery

NORMAN, Okla. -- Tailback Adrian Peterson, who finished second in the Heisman Trophy voting, should recover from shoulder surgery in time for the start of fall practice, an Oklahoma spokesman said Tuesday.

Peterson, who rushed for 1,925 yards to set an NCAA freshman record last season, had outpatient reconstructive surgery on his left shoulder Monday and started rehabilitation on Tuesday, Oklahoma spokesman Kenny Mossman said.

Peterson dislocated the shoulder during the Sooners' fall practice last season and reaggravated the injury in a game against Texas A&M on Nov. 6.

Cornerback Marcus Walker, another freshman, had similar reconstructive surgery on his right shoulder and is also expected to return in time for fall practice, Mossman said.

Walker, who made his fourth start during the Orange Bowl, hurt his shoulder during in the Big 12 title game on Dec. 4.

Both players will miss spring practice, which begins in March, Mossman said. Both had previous shoulder problems in high school, he said.
