Indianapolis Colts running back Marlon Mack suffered a fractured hand during Sunday's 33-13 win over the Jacksonville Jaguars, and will undergo more tests to determine whether he needs surgery and how long he will be out
Mack will not play Thursday night against the Texans, according to sources. Jonathan Williams became the Colts' primary running back after Mack left the game and will likely start against the Houston Texans on Thursday, with Nyheim Hines backing him up.
