He had signed with the team just ahead of a pause in league play due to the ongoing coronavirus pandemic. Mekel suited up for six games with Unicaja Málaga.
Mekel, 32, appeared in 35 NBA games across parts of two seasons. 31 of those contests were for Dallas in 2013/14, and four were as a Pelican the following season. A Wichita State alum who went undrafted in 2008, the Israel-born Mekel has been well-traveled internationally.
A three-time All-Israeli League First Teamer, Mekel is a two-time Israeli League MVP, for Hapoel Gilboa Galil in 2011 and for Maccabi Haifa in 2013.
