There is increased doubt that Kawhi Leonard will be available at the start of the Los Angeles Clippers' first-round against the Dallas Mavericks. Leonard has been out since the beginning of April with inflammation in his right knee. That's the knee Leonard has had surgically repaired in the past.

Ty Lue said his star forward has been doing shooting drills and will shoot more today. However, Leonard has yet to go through a contact practice since the knee issue flared up.

The Clippers open the first round on Sunday afternoon. LA will host Dallas in a highly anticipated matchup. Both teams are considered potential contenders to make it to the Western Conference Finals, if not the NBA Finals.
