Daniel Gafford suffered a sprained ankle during the opening practice of Dallas Mavericks training camp on Tuesday.

Gafford is expected to miss the next 2-3 weeks. The Mavs open their season on October 22 against the Spurs.

Gafford missed the final two months of last season due to a Grade 3 sprain of the MCL.

Gafford signed a three-year, $54 million contract extension over the offseason.
