Well, the Cleveland Cavaliers certainly aren't going to like this source.

Just hours after the Cavaliers completed a trade that sent Kyrie Irving to the Boston Celtics for Isaiah Thomas and other assets, Jason Lloyd of the Athletic reports that an unnamed source who has dealt with similar hip problems as Thomas says that the new Cleveland guard could be out until February.

Here is Lloyd's exact quote:

And here's @JasonLloydNBA on how important that Nets pick is to the Cavs, and some ?? speculation on IT's hip: https://t.co/vwOYYj4iKW pic.twitter.com/lVCWw5EX79 — Rachel Nichols (@Rachel__Nichols) September 1, 2017

If Thomas' hip injury is this severe, this would then mean that Derrick Rose will serve as the team's starting point guard for most of the season—if not the entire season.

While Cleveland's biggest problem of Irving being traded is now solved, they now have to worry about their new projected starting point guard being out for the majority of the 2017-18 season.
