HOUSTON -- The Houston Texans have signed running back Marlon Mack, a source told ESPN.
Mack, 26, spent his first five seasons with the AFC South rival Indianapolis Colts. His best season came in 2019, when he ran for 1,091 yards and eight touchdowns on 247 carries.
Mack joins running backs Rex Burkhead, Royce Freeman and Scottie Phillips on the Texans' roster. Houston kept five running backs on the 53-man roster to start the 2021 season, but the unit struggled in Tim Kelly's offense. The Texans finished the season last in the NFL in Football Outsiders' rushing DVOA.
