The person spoke Tuesday on condition of anonymity because the deal has not been announced. NBA.com first reported the contract.
The 6-foot-10, 241-pound Lyles averaged 8.7 points and 5.2 rebounds at Kentucky and was named to the Southeastern Conference All-Freshman team after his lone collegiate season. The forward has a 7-1 wingspan with large hands and Jazz general manager Dennis Lindsey said after the draft that Lyles can get bigger.
The team fell in love with Lyles' versatility and believes he can eventually grow into a stretch-four role with the development of his jump shot.
Lyles became the first Saskatoon-born player to be drafted into the NBA when he was picked 12th overall by Utah.
