Jayson Tatum has delivered a massive injury update that will have Boston Celtics fans breathing a collective sigh of relief ahead of a do-or-die Game 7 against the Philadelphia 76ers.

After the Celtics squandered a commanding 3-1 series lead with back-to-back losses, the stakes couldn't be higher for Saturday's showdown at TD Garden. But it was a scary moment in Game 6 on Thursday that had everyone on edge—Tatum exited in the third quarter with an apparent leg injury and didn't return, sparking fears of a calf strain or worse.

Given Boston's history of playoff heartbreak, the panic was understandable. But during his postgame press conference, Tatum put those worries to rest. "I expect to play in Game 7," he said, revealing that the issue was with his other leg—not the one he injured his Achilles on last season. "It just was a little stiff," he added. "I wasn't overly concerned."

That's music to Celtics fans' ears. Tatum was Boston's best player in Game 6, putting up 17 points and 11 rebounds before leaving the floor. Having him healthy and available is absolutely critical if the Celtics want to avoid yet another devastating postseason collapse.

But Tatum can't do it alone. He'll need more support from his teammates than he got on Thursday if Boston hopes to advance. For now, though, the biggest question mark has been answered: the superstar is ready to go when it matters most.
