Blackmon sidelined by right knee infection

SCOTTSDALE, Ariz. -- Rockies outfielder Charlie Blackmon once more is dealing with an ill-timed Spring Training injury.

Blackmon hasn't played since Friday because of an infection in his right knee. It is not clear when he will return to action.

Last spring, Blackmon was hitting .375 through March 12 and was bidding to break camp with the big club. However, he went 1-for-14 over the next five games and missed the rest of the Cactus League schedule with turf toe -- an injury that dragged into the regular season. Blackmon didn't appear in the Majors until Aug. 18. He hit .283 with two home runs and nine RBIs in 42 games.

Blackmon, 26, a second-round pick out of Georgia Tech in the 2008 MLB First-Year Player Draft, is 4-for-7 with three walks and two RBIs in four games this spring.
