Longtime NBA coach Jim Boylan is returning to the Cavaliers as Mike Brown's lead assistant, a league source confirmed Wednesday.

Boylan previously worked for the Cavaliers in the 1990s. He has worked for six NBA teams and served as interim coach of the Milwaukee Bucks this season following Scott Skiles' resignation. He was also an interim coach for the Chicago Bulls during the 20078-08 season. 

Boylan was the point guard on Marquette's national championship team in 1977.

The Cavs have now hired Boylan, Phil Handy, Igor Kokoskov and Vitaly Potapenko as assistants to Brown. Jamahl Mosley was also retained from Byron Scott's staff.
