Hall of Famer Wes Unseld has passed away at the age of 74.

The family said in a statement that Unseld had lengthy health issues, most recently with pneumonia.

"He was the rock of our family -- an extremely devoted patriarch who reveled in being with his wife, children, friends and teammates," the family said. "He was our hero and loved playing and working around the game of basketball for the cities of Baltimore and Washington D.C., cities he proudly wore on his chest for so many years."

Unseld was part of the franchise's only NBA title, in 1978, when he was named Finals MVP. He won the regular-season MVP award in 1969 and was a five-time All-Star.
