Memphis Grizzlies superstar Ja Morant could be out of action on Monday night for his team's pivotal Game 4 bout against Stephen Curry and the Golden State Warriors. The All-Star point guard has been tagged as doubtful ahead of the match, and it looks like the Grizzlies will be without their most important player on the floor on Monday.

Video footage of Morant heading into shootaround earlier in the day has surfaced and it does not bode well for his playing status for Game 4. The Grizzlies stud can be seen with a noticeable limp as he headed to the court (h/t Yahoo Sports on Twitter):

It is also worth noting that Morant did not do much in shootaround apart from dribbling the ball in his sweats towards the end of Monday's practice session:

Things aren't looking good for Morant and the Grizzlies right now and it's very much possible that he's going to be forced to sit out Monday's crucial matchup.

Morant suffered a knee injury in the closing moments of their Game 3 loss to the Warriors. He's gotten an MRI, but curiously, the Grizzlies have refused to share the results of the same.
