Rajon Rondo is out for the season after tearing his ACL in his right knee. http://espn.go.com/boston/nba/story/_/id/8887106/rajon-rondo-boston-celtics-torn-acl-rest-season .
Its very unfortunate for basketball fans that two top five point guards in their prime have gone down with ACL injuries. Let's hope for a speedy recovery for Rondo and Rose (and Davis too, although his career is probably over).
