The Brooklyn Nets were hit with yet another harsh reality after Kyrie Irving sustained an injury, landing awkwardly on Giannis Antetokounmpo's foot before being officially ruled out for Game 4 against the Milwaukee Bucks.

As it turns out, Irving was in a ton of pain that he was struggling to get up, according to Rachel Nichols of ESPN. 

That doesn't sound optimistic in any way, whatsoever. The Nets are already without James Harden, and head coach Steve Nash said he is progressing but who knows when he will return to action. Now the Nets are down to just one of their Big 3, with Kevin Durant leading the charge.

It looked absolutely painful and the fact that Irving couldn't put much pressure on it is extremely concerning for the Nets' hopes, not just in the series but in the NBA playoffs as a whole.

Without a healthy Kyrie Irving, Durant will need to shoulder almost the entire load, even though Jeff Green got cleared to play.

The Nets will aim for a more positive update regarding both Irving and Harden, but as it sits right now, this could be detrimental to their title hopes and could definitely swing the series in the favor of the Bucks.
