Tailback Marlon Mack left the Indianapolis Colts' win over the Jacksonville Jaguars early on Sunday. According to Adam Schefter of ESPN, the talented running back suffered a fractured hand in the win. He will not be available for the Colts' Thursday tilt with the Houston Texans. More tests will determine whether or not he needs surgery.

Mack finished the 33-13 win with 14 carries for 109 yards and a touchdown. His backup, Jordan Wilkins, outran him, however, as the second-year former Ole Miss Rebel tallied 116 yards on 13 rush attempts.

On the year, Mack has 192 rush attempts for 862 yards and four touchdowns. The Colts will now look to Wilkins and Nyheim Hines to carry the brunt of the rushing workload against a Texans defense that got toasted against the run against the Ravens on Sunday.

Mack has been healthy all year, but injury woes aren't anything new to the third-year back. Injuries significantly hampered his first two seasons in the NFL. In 2018, foot and hamstring problems, as well as a concussion, led him to play 12 out of 16 eligible games. Despite that, he recorded 1,011 scrimmage yards and 10 total touchdowns last season.

Indianapolis struggled to find its workhorse back before the emergence of Mack. He is just that for their offense. Amid the retirement of Andrew Luck, he has brought a sense of stability to the Colts' offense. However, they will lack that heading into a key divisional game on Thursday.

Luckily, with Quenton Nelson on the roster, the Colts' offensive line should continue to pave running lanes for anyone who rushes behind them.
