Several new players joined the Colorado football team on Tuesday.

Head coach Mike MacIntyre announced the addition of the players on the first day of the spring semester.

Five of the newcomers are early high school graduates: receiver Jaylon Jackson, defensive back Isaiah Lewis, quarterback Tyler Lytle, offensive lineman Jake Moretti and defensive end Dante Sparaco.

Defensive end Shamar Hamilton is joining CU as a JUCO transfer from ASA College in Miami.

Jackson, from Cedar Hills (Texas) High School, dealt with injuries during his junior and senior seasons, but is a highly rated prospect. He's also has great speed, having run the 100-meter dash in 10.55 seconds in high school.

Lewis, from Granite Bay (Calif.) High School, played a variety of positions in the secondary in high school and also played on offense. He played only four games as a senior because of a shoulder injury, but is fully healthy as he enters CU.

Lytle is a 6-foot-5, 205-pound quarterback from Servite High School in Anaheim, Calif. He threw for a school-record 2,759 yards this past season.

Moretti, from Pomona High School in Arvada, is one of the top in-state prospects. Originally committed to Ohio State, he changed his mind and decided to stay close to him. He missed his senior year with a torn ACL, but was an all-state player as a junior.


Sparaco is another top in-state recruit. He played at Cherry Creek High School, but transferred to IMG Academy in Florida for his senior year. He had 71 tackles, six sacks and three forced fumbles for IMG, which ranked No. 2 in the country by USA Today.

Chance Lytle and Colby Pursell also began classes on Tuesday. The two offensive linemen were part of CU's 2016 recruiting class but delayed enrollment one semester.

CU is also welcoming back Evan White. The junior safety, from Cherokee Trail High School, was dismissed from the team a year ago. He started three games as a freshman in 2014.

All of the newcomers are working out with the rest of the team and will take part in spring football, which begins Feb. 22.
