Young sustained the concussion and whiplash in a car accident before last month’s NBA draft. The Celtics chose the 6-foot-6 swingman 17th overall with its second first-round pick — Boston selected Oklahoma State guard Marcus Smart sixth overall with the first — but held Young out of practices and the competition for rookies and free agents in Orlando.
Young said Tuesday that he was cleared to practice a “few days ago”, adding that the scary rear-end collision showed him “how fast things can change. It really opened my eyes about things and I’m very blessed that I’m here and still playing.”
