UPDATE, 6:13: The Rays have sent minor-league medical training coordinator Mark Vinson to Birmingham to be with Downs, and Downs' mother is also en route. The condition is not considered life-threatening. Down was placed on the disabled list today and is not expected to pitch again this season. Rays players also signed a card for Downs.

UPDATE, 3:13: The Rays issued a statement saying Downs remains hospitalized in "serious, but stable" condition. He was struck on the left side of the head.

DEVELOPING: Darin Downs, a pitcher for the Rays' Double-A Montgomery (Ala.) team, is in the intensive care unit of a Birmingham, Ala., hospital with a fractured skull after being hit by a line drive in Monday's game, the Montgomery (Ala.) Advertiser's Stacy Long reported.

Downs is alert and conscious, with doctors monitoring cranial bleeing and swelling, Biscuits spokesman Jon Laaser told the paper.

Downs, a 24-year-old lefty, was hit on the head during the fifth inning by a line drive by Christian Marrero, with the ball deflecting into the Barons' dugout for a ground-rule double.

Downs never lost consciousness and was taken by ambulance to St. Vincent's Hospital in downtown Birmingham.

Downs was 12-4, 2.00 at Class A Charlotte before being promoted to the Biscuits, and was making his second Double-A start.

Also, new White Sox pitcher Jake Peavy will make a rehab start for Charlotte today against Triple-A Durham.
