Clippers' point guard Shaun Livingston has resumed basketball-related activities after nearly eighteen months of rehabilitation, according to The Los Angeles Times.

He has been cleared medically to play one-on-one and has been able to dunk without pain recently. However, it still appears doubtful that Livingston will be cleared to play in the Summer League.

Livingston has been on the shelf since February of 2007 when he injured his knee in a game against the Bobcats.

He will become an unrestricted free agent on July 1 if the Clippers do not offer him a salary starting at $5.8 million.
