Jose Calderon sat out Friday's scrimmage due to a sore left hamstring.

Calderon has been limited over the past three days.

The Dallas Mavericks are also dealing with injuries to Devin Harris and Shane Larkin, which will open up time for Gal Mekel.

“This is the opportunity of a lifetime for any guy coming to a new situation with some guys banged up,” Carlisle said. ““Gal, he’s picking things up as he goes along. We need him and we need him to play.”
