ESPN's Adrian Wojnarowski reported that "after isaiah thomas underwent a physical today, Cavs still evaluating injured hip and weighing options with completion of Irving deal." If Thomas failed the Physical Exam, then the Cavaliers could decide to halt the deal that would have sent Isaiah Thomas, Jae Crowder, Ante Zizic, and the Brooklyn Nets' 2018 unprotected first-round pick to Cleveland and Kyrie Irving to Boston.

Thomas' injury

Thomas sustained the hip injury during Game 6 against the Washington Wizards in the NBA playoffs. He willed himself to play Game 7 and led his team to the Eastern Conference Finals.

Against the Cavaliers, he was only able to play in Game 1 and the first half of Game 2 before his body could take no more.

Cavs and Celtics cannot back out

The cancellation of this trade would be devastating for both sides. The Cavaliers have clearly let the world know that they were only waiting for the right opportunity to trade Irving this off-season. Now it is unlikely that they will receive as good an offer as what Boston presented. The Cavaliers will feel the pressure of ridding themselves of Irving and could ultimately have no option but to take less from a different team.

The Celtics cannot keep Thomas either. Isaiah felt he had played his heart out for the organization and therefore felt immensely disappointed to hear he was traded.

In the event that this deal gets abandoned, the Celtics would have no option but to trade their heart-broken All-Star. However, his price would fall considering Boston's urgency of trading him, as well as Thomas' suspect health. Now everyone knows that Isaiah's hip injury, which he declined to repair surgically, is more serious than many could have imagined.

Cavaliers should assume the risk

If the Cavaliers choose to retreat, the Celtics should still find a way to make the deal still happen. Adding a second round pick could be a solution. The Celtics value Irving too much to let him slip out of their hands at this stage and in this manner. In addition, both teams have to think about their fans who have already burnt jerseys of Irving and Thomas, right?

On more serious note, the Cavaliers have to take responsibility for agreeing on a deal of an enormous magnitude before doing their due diligence, which includes checking on Thomas' health status in this case. A source involved in the process of Thomas' medical clearance told ESPN that it was "a very sensitive situation". It would turn into an even more sensitive situation in Cleveland and Boston if the deal ultimately does not happen.
