After a career season, Thomas was ultimately shut down after the Celtics lost the first two games against the Cavaliers in the Eastern Conference Finals. While no surgery was required, the two-time All-Star has been rehabilitating the injury during the offseason.

If Thomas is not cleared, there are two options for both teams. In the first scenario, the Cavaliers could ask for another player and/or additional draft pick to still complete the trade. In the second scenario, the Cavaliers could void the trade and all the players involved would return to their respective teams.

Should the Cavaliers ultimately void the trade, it will be interesting to see what happens with Irving. While there are numerous teams interested in him, many believe the Cavaliers won the trade with Thomas, Jae Crowder, Ante Zizic, and 2018 Brooklyn Nets first round draft pick.
