(CNN)Cliff Robinson, NBA All-Star who played with the Portland Trail Blazers and Phoenix Suns, has died at the age of 53.
"The UConn Basketball family mourns the loss of a legendary player and person, Clifford Robinson," the University of Connecticut Men's Basketball Team tweeted Saturday morning. Robinson was a former player for the university.
Robinson's cause of death is unknown at this time.
The former player from Buffalo, New York, was drafted out of the University of Connecticut to play for the Portland Trail Blazers in 1989 and was a critical player for the eight seasons he played there.
"He was our first great player... he came from a difficult background in Buffalo, I watched him evolve as a man... he was a good man, had a great career, and was instrumental in a lot of the great things that happened at UConn," former Huskies coach Jim Calhoun told David Borges of Hearst Connecticut Media.
Robinson helped lead the Trail Blazers to two NBA Finals and won the 1993 Sixth Man of the Year Award before playing for the Phoenix Suns, Detroit Pistons, Golden State Warriors and New Jersey Nets. He was selected as an All-Star once, in 1994.
Nicknamed "Uncle Cliffy," the beloved player retired in 2007.
