The Toronto Raptors are pursuing Masai Ujiri to become the team's top basketball executive, according to sources.

Ujiri was named the 2013 NBA Executive of the Year for his work as general manager of the Nuggets.

Ujiri's contract with the Nuggets expires this summer and he has been in discussions on an extension.

Korn/Ferry International, the search firm hired by MLSE to search for a new GM for the Raptors, has identified Ujiri as its top candidate.

MLSE has until Monday to make a decision on whether to retain Bryan Colangelo, who could stay with the franchise under a new decision-maker.

Ujiri worked for three years with the Raptors under Colangelo before becoming GM of the Nuggets.
