Toronto's coaching search reportedly had narrowed down to Nurse and San Antonio assistant coach Ettore Messina. Casey was sacked after the Raptors were swept out of the second round of this year's playoffs by Cleveland.
Nurse, 50, spent 12 seasons coaching in Europe and has six seasons of coaching experience in the G-League, where he won two championships and a Coach of the Year award.
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.More news: Porsche Unveils 911 Speedster Concept to Celebrate 70th Anniversary
