North Carolina tight end Brandon Fritts suffered a torn right ACL during spring practice, the school announced.
In 2018, he tore his left ACL in spring practice and missed the entire season.
A school news release said he has been ruled out for the spring and "will continue to be evaluated heading into the fall."
The 2019 season will be his sixth, and it's his final year of eligibility. He entered his name in the NCAA transfer portal in December but changed his mind and decided to stay with the Tar Heels.
"Obviously, I'm disappointed with this injury, but I'm going to attack the rehab process and see what might be possible during the fall," Fritts said in a statement. "I made a commitment to be at North Carolina because I wanted to play with my teammates and this coaching staff, and I'm going to work to try and make that a possibility."
Head coach Mack Brown also issued a statement about Fritts.
"I feel terrible for Brandon, but he's a tough young man and he'll work really hard during the rehab process," Brown said. "He's been through this before, so that may help him as he navigates the next few months. ... We'll do everything we can to support him, pick him up, and make sure he knows that he brings a ton of value to what we're doing, both on and off the field."
In his three seasons at North Carolina, Fritts has caught 47 passes for 439 yards and nine touchdowns.
