What Boo Carter Brings to Colorado Buffaloes

Boo Carter is a 5-11, 200 pound defensive back out of Cleveland, Tennessee. As a four-star high school recruit in the class of 2024, Carter stayed close to home and signed with the Tennessee Volunteers.

Carter played 2024 and 2025 with the Vols. In 22 games, he tallied 63 total tackles, 7.5 tackles for loss, three passes defended, three forced fumbles, two sacks, and one interception. He also was Tennessee’s punt returner.

He is rated as a four-star transfer and the No. 4 safety in the 2026 transfer class.

The End of Boo Carter With the Tennessee Volunteers

His tenure in Knoxville ended on a sour note. In mid-November of 2025, Carter was released from the team after he did not come to the Vols homecoming game against the New Mexico State Aggies. This was months removed from the summer time when Carter had spent time away without permission from the team.

In the end, it reached a boiling point that resulted in Vols coach Josh Heupel dismissing him. Heupel spoke to reporters shortly after the release, stating that he didn’t have regrets.

“Not regretful…At the end of the day, it’s our job as coaches to try to help mold these guys,” Heupel said. “Sometimes it work out sometimes it doesn’t. At the end of the day, we’re moving forward.”

Carter and Heupel clearly did not see eye to eye during this as Carter posted on his social media after the release, saying that his time with Tennessee was over due to injury.

“I’d like to take this opportunity to thank The University of Tennessee Coaches, administrators and fans for a wonderful 2 years,” Carter said. “Unfortunately my season has been cut short due to injury. I have decided to enter the transfer portal.”

Now, Carter is a member of Colorado’s 2026 transfer class. The Buffs are looking to bounce back from a disappointing 2025 season in which they went 3-9. If “Coach Prime’s” transfer portal moves hit, there is no question Colorado can be one of the most improved teams in the Big 12 in 2026.
