“I was in shock,” Kemba Walker said via ESPN. “In those kinds of situations, it's kind of hard to say anything. You just don't even know what to say sometimes. We're going to miss him for the time that he's out.”

You really hate to see it happen, especially to someone like Hayward.

The man has been working his butt off over the past two years to finally regain his old form and more importantly, his confidence.

Hayward returned last season after suffering a gruesome injury on the opening night of the 2017-18 season. He struggled to find his rhythm the entire year and was clearly a shell of his former self.

Hayward will reportedly see a hand specialist to see if surgery is required to repair the broken hand. Should the doctors suggest he go under the knife, the 6-foot-8 forward will likely see another extended absence.

Nevertheless, while it isn't as devastating as his broken ankle two years ago, it's still gotta be frustrating for Hayward. He was just beginning to play at a high level again and looked poise for a bounce back campaign this season. Through the Celtics' first seven games, Hayward was averaging 20.9 points, 7.9 rebounds, and 4.6 assists.

As for the Celtics, Kemba and company will have to keep the ship afloat as they wait on Hayward's eventual return this season.
