Kawhi Leonard has been diagnosed with a "partial tear" in his left shoulder.

Leonard was ruled out of Sunday night's game at Portland, and the Spurs plan to evaluate Leonard over the next couple of days of its current road trip.

"I don't think it will be a while," Gregg Popovich said.

The latest setback represents yet another roadblock for Leonard in his return, as he missed the first 27 games of the season rehabilitating from quadriceps tendinopathy.
