San Antonio Spurs forward Kawhi Leonard will not make his season debut against the Phoenix Suns on Saturday as originally hoped, sources told ESPN's Michael C. Wright and Adrian Wojnarowski on Friday.

A decision hasn't been finalized for Leonard's return, but the Spurs are now targeting Tuesday's road game against the Dallas Mavericks, the sources said.

Right quadriceps tendinopathy has kept Leonard out of all 25 of San Antonio's games. On Monday, when addressing his possible return, Leonard said "soon to come."

On Friday before their 105-102 win over the Celtics, Spurs coach Gregg Popovich said he's only worrying about the guys who are healthy and available right now.

"Whoever is not there is not there. We don't worry about him [Leonard] or think about it too much. We've got to take care of as much as the business as we can, just like Boston is doing. I guess they know he's not coming back for right now. In our case, when he gets there, he gets there. In the meantime, a lot of the guys are getting time. We're playing a lot of different people, a lot of different combinations. Some nights it doesn't work out really well. Other nights, it looks really good. But I think down the stretch it will help us."

A two-time NBA All-Star and two-time NBA Defensive Player of the Year, Leonard averaged career highs in points (25.5) and assists (3.5) last season, while also averaging 1.8 steals. Leonard hasn't suited up to play for San Antonio since Game 1 of the Western Conference finals, a series he couldn't continue due to a sprained ankle.

As part of the recovery from quadriceps tendinopathy, Leonard has worked through a rehabilitation process comprised of several steps such as individual work, two-on-two and three-on-three drills, before receiving clearance to practice with the team. Leonard had been working out with Tony Parker, as he recovered from a ruptured quadriceps tendon, as well as former Spurs players Matt Bonner and Tim Duncan.

The Spurs, already without Leonard and Kyle Anderson, lost Danny Green in the first half of Friday's game.

Green left with tightness in his left groin. There was no update on the severity of the injury after the game, and he was listed as questionable for Saturday's game.

Green is averaging 9.7 points in 28.8 minutes per game this season.
