The Indianapolis Colts have signed undrafted free agent defensive back Ashton Hall, a league source said.
Hall (5-10, 186) played his college ball at Marshall University, totaling 218 tackles and three interceptions. Hall earned honorable mention All-Conference USA honors in 2009.
Hall ran a pedestrian 4.63 in the 40-yard dash during his pro day in March, but demonstrated his athleticism by posting a 39.5" vertical leap and a 10'04" broad jump. Hall set Marshall's vertical leap record (44"), besting the previous mark set by Randy Moss.
Signed by the Baltimore Ravens in May, Hall was released when the Ravens ended their off-season workouts.
