Dallas Mavericks star Luka Doncic will miss Monday's clash against the Milwaukee Bucks due to an ankle injury.
Doncic sprained his right ankle during the Mavs' 122-118 overtime loss to the Miami Heat on Saturday.
An NBA MVP contender this season, the 20-year-old was set to face fellow star Giannis Antetokounmpo when the Mavericks visit the Bucks.
However, he was ruled out on Sunday, with the Mavs writing on Twitter: "#Mavericks guard Luka Doncic suffered a right ankle sprain in the first quarter of last night's game against Miami.
"Doncic will not travel with the team to Milwaukee for Monday night's game against the first-place Bucks."
The Mavericks are 17-8 and sit third in the Western Conference, but Doncic's absence is a huge blow.
Doncic is enjoying a stellar season, averaging 29.3 points, 9.6 rebounds and 8.9 assists per game.
