Jaylon Jackson's football career is on hold again.
Colorado head coach Mike MacIntyre confirmed Monday that the true freshman receiver broke his ankle during a scrimmage at Folsom Field on Saturday.
Jackson, who had successful surgery on Saturday night, will miss the entire season and use his redshirt.
"He was having a good day. It's a shame," MacIntyre said.
It's the third year in a row Jackson has had a major injury.
As a junior at Cedar Hill (Tex.) High School in 2015, he had a torn ACL and missed all but one game of that season, returning for a playoff game. He then tore the same ACL before his senior year and missed that entire season.
Despite three major injuries in three years, Jackson is eager to return, MacIntyre said.
"He's extremely positive and he'll get it back and be ready to go again," he said.
The 5-foot-10, 175-pound Jackson enrolled at CU in January and went through spring drills. Although he was likely to redshirt this year anyway, he was having a good fall and showing flashes of being a playmaker in the slot.
Noyer on track
While sophomore Steven Montez is projected to start at quarterback, redshirt freshman Sam Noyer is having a good camp, as well.
MacIntyre is often quick to praise all of his quarterbacks, including Noyer, true freshman Tyler Lytle and walk-on Casey Marksberry.
Noyer, from Beaverton, Ore., is in the same position Montez was in last year, as a redshirt freshman with no experience.
"I would say he's about right where was Steven was (last year)," MacIntyre said. "As a matter of fact, he's in better shape than Steven was this time last year because Steven was just coming off that ankle (injury), so he wasn't in as good of shape as he should have been."
Last season, learning the CU playbook was the toughest challenge for Beau Bisharat.
This season, the true sophomore running back feels comfortable and more ready to contribute to the offense.
"Last year, I didn't know the plays very well," he said. "This year it's a big advantage for me just knowing the plays and knowing how to read a play or when to be patient and when not to be patient. Now it's really just competing and working hard and trying to earn my spot."
Bisharat was a valuable part of CU's special teams units last year as one of just four true freshmen to play. Offensively, he was used as a blocker late in the year, but carried the ball just 15 times for 45 yards.
He is now very much in the mix for the No. 2 spot at tailback, behind starter Phillip Lindsay.
"(The competition) is for sure fueling me," he said. "Everybody knows that we're all competing."
Bisharat is the biggest of CU's tailbacks, at 6-foot-2, 220 pounds. He's gained about six or seven pounds of muscle since last season, when he played at about 212-213 pounds.
Between his playbook knowledge and added strength, Bisharat said, "I'm better off for sure than I was a year ago going into the year."
After reviewing Saturday's scrimmage, MacIntyre said he was pleased with how the defense "flew around." He's also been impressed with the play of CU's young inside linebackers — redshirt freshman Akil Jones and true freshmen Nate Landman, Jonathan Van Diest and Carson Wells. ... MacIntyre was also pleased with the running game and felt the offensive line "did a good job." ... Part of the scrimmage involved situational football, and MacIntyre was pleased with how the offense handled being backed up near the end zone, and how they worked the two-minute drill. ... Because of inclement weather, the Buffs practiced indoors Monday for the first time in camp.
