Purdue running back Tario Fuller will undergo ankle surgery later this month, head coach Jeff Brohm said at his weekly press conference on Monday.

Fuller played in the first three games of the season for the Boilermakers and was the top rusher through the non-conference schedule. But an ankle injury has kept the running back sidelined since B1G play started on Sept. 23. Though there have been hopes that Fuller could return at some point this season, it doesn’t appear that will happen.

In the first three games, Fuller rushed for 261 yards and two touchdowns on 43 attempts. He was outstanding against Ohio, toting the ball for 142 yards and a touchdown while averaging 8.9 yards per carry.

He’s still Purdue’s second-leading rusher statistically through 10 weeks of the season.

The Boilermakers have used a running back-by-committee approach this season, using several ball-carriers. D.J. Knox is currently the top yardage-getter with 409 yards but Markell Jones and Richie Worship have also seen several touches this year.
