Milwaukee Bucks star Damian Lillard has been cleared of his deep vein thrombosis and is no longer on blood-thinning medication, sources told ESPN on Thursday.

Lillard will not play Saturday for Game 1 of the Bucks' playoff series against the Indiana Pacers, and sources told ESPN the veteran guard will have a period of time to resume contact workouts and ramp up for a return.

Doctors have told Bucks officials that the speed of Lillard's recovery has never been seen before, but it occurred because of early treatment, detection and specialists working on him before a formal diagnosis, according to sources.

The Bucks said Tuesday that Lillard was making "significant improvement on his deep vein thrombosis" and that the nine-time All-Star will increase his on-court activity, but did not offer a clear timetable for his return.

The Bucks announced last month that Lillard, 34, would be sidelined indefinitely. The team said at the time that Lillard had been using a blood-thinning medication to stabilize the clot.

Coach Doc Rivers added earlier this month that he was optimistic Lillard would return at some point, but acknowledged that the team also was prepared for the nine-time All-Star to miss the rest of the season.

Lillard was averaging 24.9 points and 7.1 assists before being sidelined for Milwaukee's final 14 games of the regular season. The Bucks went 10-4 in those contests and ended the season on an eight-game winning streak.
