Luka Doncic is reportedly unlikely to play for the Dallas Mavericks in Game 2 of their first-round series against the Utah Jazz.

The Mavericks superstar missed the potentially damaging 99-93 home defeat to the Jazz in the series opener as he recovers from a calf strain sustained in the final game of the regular season.

Although Doncic took part in light shooting drills over the weekend, an ESPN report said the Slovenian "would have to make dramatic improvement" ahead of Monday's game in order to be cleared to return.

That report at least provided more clarity than Mavericks coach Jason Kidd was able to offer.

"Yesterday was another good day, and today he's back on the court, so that's a plus," Kidd said on Sunday. "And we'll see how he feels tomorrow."

Dallas will fear another defeat in Doncic's absence and a 2-0 deficit before going on the road.

Despite averaging 33.5 points – the most of any player to feature in 13 or more postseason games – Doncic has never won a playoff series.
