Wojnarowski reports that Nurse accepted the job on Tuesday morning.
The Toronto Raptors didn't have to go far to find the man who will be the ninth head coach in franchise history.
A graduate of the University of Northern Iowa, Nurse was 23 when he became head coach of Grand View College, making him the youngest college basketball coach in the U.S.
The 50-year-old Nurse is known for his offensive skills as a coach, winning the D-League championship in 2010-11 and 2012-13 before joining the Raptors.
In charge of the Raptors' offence, Nurse played a pivotal role in successfully reinventing the way the team played last season.
After a stint as an assistant for the Dallas Mavericks, Casey took over as Raptors' coach from Jay Triano to start the 2011-12 season. He also won two rings at the minor-league level.
Lewenberg noted that if the Raptors passed on Nurse as head coach, they risked losing him altogether as he finished atop a Yahoo poll from early April among executives that tabbed him as the top head coaching prospect among National Basketball Association assistants.
Casey was sacked last month and was hired by the Detroit Pistons on Monday. During his seven-year tenure, Casey went 320-238 (.573).
