The blockbuster deal between the Boston Celtics and Cleveland Cavaliers that would swap Isaiah Thomas (and considerably more) for Kyrie Irving is approaching its initial deadline.

The Cavaliers have expressed concern about the state of Thomas' hip, threatening to void the trade if the Celtics don't offer more compensation. The Celtics, meanwhile, believe they were upfront with all the necessary information and have indicated the agreed-upon deal should be enough.

Cleveland has a limited timeframe in which it can either decide to void the trade and fail Thomas on his physical, accept the deal in its current state, or renegotiate for further compensation.

Let's briefly break down where things stand in Q&A format.

1. When is the deadline?

If the Cavaliers want to void the deal, they will need to do so by 10 a.m. on Thursday morning.

2. Wait, so why did I hear Wednesday at 10 a.m.?

The best guess is because there WAS a deadline on Wednesday at 10 a.m.: The deadline to send in all the physicals. Obviously, Thomas's physical had already come through, because the Cavaliers said they were concerned by what they found. That seemed to confuse a lot of people online. The deadline to VOID Thomas' is deal is Thursday morning.

3. What happens if the Cavaliers do nothing?

The trade goes through as it was called into the league office: Kyrie Irving to Boston, and Isaiah Thomas, Jae Crowder, Ante Zizic and the 2018 Brooklyn Nets pick to Cleveland.

4. What does the deadline mean?

It means this thing likely has an end in sight. Both teams can agree to extend it, but if they do, you can bet we'll at least get some clarity as to where the talks are currently.

5. So this thing might drag out even further?

Honestly, that seems a little doubtful. This is speculation, but the Cavaliers have pretty clearly been giving teams a chance to pitch them better deals during this process (a shady maneuver at best), and the Celtics probably won't be eager to give them a chance to continue. Cleveland, meanwhile, probably won't want to lose this deal. If the Celtics won't agree to an extension, the Cavaliers will be forced to either fail Thomas and void the trade or agree to the deal.

If this package remains the best Cleveland has been offered overnight, everything might very well be wrapped up by 10 a.m. on Thursday.

Praise be.
