Baseball: Walker injuried on feilding play

St. Louis Cardinals right fielder Larry Walker sprained his right knee when he slipped fielding a ball near foul territory Sunday, but the injury is not believed to be serious.

"I'm assuming he's going to be OK," manager Tony La Russa said. "Nobody told me otherwise."

Walker was removed in the fifth inning of Sunday's game against the Los Angeles Dodgers and had an MRI exam that revealed a small bone bruise. Trainer Barry Weinberg said Walker was day-to-day and conceivably could play Monday at San Diego.

Walker, who is batting .305 with 12 homers and 38 RBIs in 62 games, limped for several minutes but was able to trot off the field after medical attention.

"That's always a good sign," Weinberg said. "He's one of those very tough, tough individuals."

Walker was injured when he slipped fielding a single by Jose Hernandez. He also slipped in the outfield fielding a hit by Robin Ventura in the fourth, but was not hurt.
