File-This Nov. 10, 2019, file photo shows Indianapolis Colts safety Khari Willis (37) tackling Miami Dolphins running back Kalen Ballage (27) during the second half of an NFL football game in Indianapolis. Ballage’s historically unproductive season ended Tuesday, Dec. 3, 2019, when he was placed on injured reserve by the Dolphins. Ballage hurt his left leg in Sunday’s victory over Philadelphia. The second-year pro finishes the season with 135 yards in 74 carries. His 1.8-yard average is the worst by a running back with at least 70 carries since Phil Sarboe had a 1.2-yard average for two teams in 1936. (AP Photo/Darron Cummings, File)
