Lillard, who was sidelined last week with a deep vein thrombosis in his calf, could reportedly return to the court sooner than expected.

With two high-profile NBA stars suffering from blood clots recently, we asked doctors how they happen and if they are occurring more often.

NBA insider Shams Charania of ESPN provided a major health update on Milwaukee Bucks star point guard Damian Lillard, who is currently out with blood clots in his right calf. Charania reported that Lillard's blood clots are getting smaller. There is optimism that the All-Star can get cleared for full-contact workouts in the next week or so.
