Luka Doncic will undergo an MRI after being forced out of the Dallas Mavericks' loss to the New Orleans Pelicans with a thigh issue, having described his injury as "not good".

Doncic recorded 15 points and eight assists before exiting in the third quarter of Wednesday's 113-106 defeat, a result that saw the Mavs slip to eighth in the Western Conference.

The four-time NBA All-Star appeared to be in pain after going up for a 15-foot jump shot, and his condition must be assessed ahead of the first game of a double-header against the Memphis Grizzlies on Sunday.

Asked about his thigh after the loss to New Orleans, Doncic said on Wednesday: "It's not good.

"I didn't get hit. So this is kind of weird for me. I don't really know what it is. I can feel it mostly on the jump shots because you need both legs, so pushing off has been really hard for me.

"Tomorrow, we're going to do an MRI. We'll see if everything is fine. Just ice and therapy and that's it. We'll see more tomorrow."

Doncic also revealed he felt discomfort in the same area before a 142-116 win over the San Antonio Spurs on February 24, with the injury lingering since then.

"I think it was the second game after the All-Star break, something like that," Doncic said, when asked when he first sustained the problem.

Coach Jason Kidd said: "I think we all can see he's not moving well. Shooting, defense – it's affecting everything. He's trying to fight through it and help his team-mates. But he had to leave there.

"Hopefully it's not something serious. We have a couple of days here before we play Memphis. Hopefully he's back soon."
