Newly acquired center Ryan Hollins is expected to wear No. 50 for the Boston Celtics.
Hollins has worn Nos. 1 (Bobcats, Mavericks, Timberwolves), 15 (Bobcats), and 5 (Cavaliers) during his six NBA seasons. In Boston, Nos. 1 (Walter Brown) and 15 (Tommy Heinsohn) are retired, while it doesn't appear Kevin Garnett will relent his No. 5.
Only four other players in Celtics' history have worn No. 50 -- Greg Kite(1984-88), Matt Wenstrom (1994), Theo Ratliff (2007), and Eddie House (2008-10).
