FORT COLLINS — Colorado State’s trio of productive backs will be down to two for the Famous Idaho Potato Bowl as true freshman Marvin Kinsey Jr. sustained a torn ACL during Saturday’s practice, head coach Mike Bobo confirmed.

Kinsey had announced his injury on Twitter during the day, saying: “Sad to say my season has come to an end, due to a torn ACL. This is only a minor setback for a major come back . #RamNation.”

A true freshman out of Atlanta, he sits third on the Rams depth chart and leaders, rushing for 546 yards on 93 carries and seven touchdowns. He holds the best single-game total for a Ram back this year with 127 yards in the win over New Mexico, also breaking off the longest run for a back in the Bobo era with a 75-yard scoring run. In that game, all three CSU tailbacks — Dalyn Dawkins and Izzy Matthews — rushed for more than 100 yards.

Bobo, out on the road recruiting this week, confirmed the injury took place over the weekend.

“Marvin Kinsey Jr., suffered a non-contact injury during Saturday’s practice,” Bobo said in a release through communications director Paul Kirk. “I feel for Marvin, but the medical staff expects a full recovery and he is in good spirits.”

Earlier in the year, true freshman quarterback Collin Hill torn an ACL in the game against Utah State. He’s already had surgery, and Bobo stated at the time he expects Hill back for spring practice in a limited capacity. With the timing of Kinsey’s injury and the normal six-to-12 month recovery period, it would be doubtful Kinsey will be able to take part in spring camp.

For the bowl game, the Rams still have a talented duo in Dawkins, who leads the team with 801 yards and Matthews, second with 705 and a team-leading 12 rushing scores. Next on the depth chart would be Bryce Peters, who has 11 carries this year for 43 yards.

The Rams have two other injuries they are monitoring: linebacker Kiel Robinson (high ankle sprain) and nose tackle Josh Lovingood (knee sprain). Bobo said after last Friday’s practice he would anticipate both being able to play in the bowl, with Robinson the further of the two from being ready since his injury came in the 63-31 win over San Diego State to close the season. Lovingood was injured in the New Mexico win.
