CLEVELAND -- While the Cavs had yet to make a formal request to the Celtics for additional compensation for Kyrie Irving Monday, pictures circulated of Jae Crowder wearing Cleveland gear for workouts.

The Cavs are still mulling whether to ask Boston for something else besides Isaiah Thomas, Crowder, Ante Zizic, and Brooklyn's No. 1 pick for Irving because of Thomas' injured right hip that could keep him out an extended period of time this season.

As of Monday afternoon, two sources told cleveland.com that there was nothing new to report on those deliberations, with one source saying the Celtics were still waiting to hear what (if anything) extra the Cavs wanted for Irving.

But it's a fluid situation that could change at any moment -- much like virtually everything with the Cavs this offseason.

Thomas missed the final three games of the Eastern Conference finals because of a torn labrum, and since he underwent his physical Friday in Cleveland the Cavs have made it known they're weighing their options on the trade. The deadline to complete the trade is Thursday, though both teams could agree to an extension.

Crowder completed and passed his physical for the Cavs last week, a source said, and is looking forward to joining the three-time defending Eastern Conference champs.

Cleveland could accept the deal as it was originally constructed, ask Boston for more -- such as another young player like second-year man Jaylen Brown or rookie Jayson Tatum -- or for an additional draft pick. A league source expected the Celtics to resist the Cavs' request, especially for a significant piece like Brown or Tatum, unless "Danny Ainge feels like (the Celtics') doctors ruined Thomas."

The source expected the trade to ultimately be completed because of the value of the Brooklyn pick -- a potential lottery selection -- and Crowder's versatility as a defender and his team-friendly contract. Crowder has three years left on his deal worth $6.8 million, $7.3 million, and $7.8 million, respectively.

Training camp starts in one month, and onlookers believe the Cavs don't want to have to try and trade Irving again, while Boston would be left without a reliable point guard if Cleveland voids the deal.

LeBron James, who leaves this week for his annual Asian tour with Nike, is likely to host his Cavs teammates for pre-camp workouts in southern California in September, though the precise dates have not been determined, a source said.

Thomas did not undergo surgery, and Ainge, the Cs' team president, said after the trade was announced last week that he thought Thomas would miss the start of the season.

The Cavs will not even speculate privately how bad they believe Thomas' injury to be. Thomas was in Las Vegas over the weekend for the Mayweather-McGregor fight.

In the meantime, Crowder worked out at Georgia Tech Sunday in Atlanta wearing Cavaliers-issued gear, near his family home.

Crowder, 27, lost his mother to cancer last Tuesday, hours after he was traded.

Another picture of Crowder in Cavs gear while standing in a hospital room also made its rounds on the Internet, which may have been taken while undergoing his physical for Cleveland.
