Lang (6-5, 280), the No. 11-ranked player in the Sentinel's Central Florida Super60, and Boone teammate DB Joe Martinson visited UCF this past weekend for the Knights' first junior day.
Lang now has seven offers with Florida State, UCF, USF, FIU, South Carolina and Texas Tech on board so far.
Boone coach Phil Ziglar confirmed the Kansas offer to Lang on Wednesday and said the Jayhawks are also very interested in Martinson (5-11, 180), who has no official offers yet. He is the No. 41 player in the Central Floria Super60.
"They are very interested in Joe and I talked to coach Wimberly (Kansas safety coach Robert) and he said they would get back with me about Joe next week," Ziglar said.
