DALLAS -- Toronto point guard Kyle Lowry is not active for Wednesday night's game against the Dallas Mavericks after leaving the Raptors' last game with a sprained right ankle.

Lowry, who was acquired this past summer from Houston, injured his ankle Tuesday night against Oklahoma City and left with 1:29 remaining in the first half. The seventh-year guard is averaging 18.3 points and 6.3 assists through four games.

Jose Calderon, last season's starter before Lowry's arrival, and John Lucas III are expected to share point guard duties.
