OWINGS MILLS, Md. (AP) - Ravens coach John Harbaugh says rookie cornerback Jimmy Smith will be sidelined ``a few weeks'' with a high ankle sprain.

Smith hurt his left ankle on the Ravens' first kickoff early in the first quarter of Sunday's 35-7 win over Pittsburgh. Baltimore's top draft pick was expected to play a backup role on defense.

Harbaugh says Smith is wearing a boot, walking with the aid of crutches and had an MRI. The coach says ``it's going to be a few weeks. We'll have to see how it plays out. Hopefully he's a quick healer.''

Smith was listed second on the depth chart at cornerback for Sunday's game.
