"It is with a profound deal of sadness that we mourn the sudden loss of a beloved son, father and friend, Sean Rooks. Words simply cannot express the heartbreak and shock our entire organization is feeling over this loss," 76ers co-managing owners Josh Harris and David Blitzer said on behalf of the team.

Rooks played 12 seasons after being selected in the second round of the NBA draft by Dallas in 1992. He averaged 6.2 points in 749 games with seven teams.

His interview with the Knicks was first reported by Yahoo Sports.

Lute Olson, who coached Rooks in college, called it a "terrible loss for Arizona basketball."

"This is just a horrible shock," Olson said. "Sean was such a wonderful young man with a great disposition. During his time at Arizona, he was always one of the most pleasant individuals to be around."

Rooks' son, Kameron, is a 7-footer playing for California. He also is survived by another child, Khayla, and his mother, Deborah Brown.
