The Boston Celtics and San Antonio Spurs reportedly have not held productive talks regarding a potential trade for disgruntled swingman Kawhi Leonard.

According to the Boston Herald's Steve Bulpett, the Celtics and Spurs had a "brief discussion" on Wednesday that featured "no real negotiation."

"It was the first contact between the teams since before the draft, but even those talks did not include the C's making an offer," Bulpett wrote. "That brief call, according to two league sources, went nowhere."

Earlier Wednesday, ESPN.com's Adrian Wojnarowski, Brian Windhorst and Ramona Shelburne reported the Celtics—along with the Cleveland Cavaliers, Los Angeles Clippers and Philadelphia 76ers—were one of the teams who had submitted an offer for Leonard.

The Los Angeles Lakers have also been in hot pursuit of Leonard. However, the Spurs have been reluctant to engage them to this point.

Shelburne previously reported the Spurs "shut the door" on one of the Lakers' initial inquiries. That said, Wednesday's update mentioned San Antonio hasn't ruled out trading Leonard to a Western Conference team, contrary to a report from USA Today's Sam Amick.

As for Boston, Bulpett noted the Celtics "would like to be involved" if the Spurs intensify their pursuit of a trade partner. For now, though, he cautioned "there has been nothing yet to indicate they have a realistic chance."

If the Celtics get serious about trading for Leonard, who will be an unrestricted free agent next summer, they could offer a compelling package of assets.

Even if Jayson Tatum is off the table, Boston has compelling trade chips in Jaylen Brown, Terry Rozier, the Memphis Grizzlies' top-eight-protected first-round pick in 2019 and the Sacramento Kings' 2019 first-round pick, which is protected only for the No. 1 overall selection.
