Brian McIntyre is reporting that the Colts have signed DB Ashton Hall. Hall, an Undrafted Free Agent (UDFA), played his college ball at Marshall. He was originally signed by the Baltimore Ravens, but was released immediately following off-season workouts. Hall disappointed in the 40-yard dash, running it in 4.63 seconds, but seemed to shine in the athleticism drills, posting a 39.5" vertical-leap and 10.04" broad jump. Hall received honorable mention All-Conference USA honors in 2009.
