The Cleveland Cavaliers have been dealt a major blow after it was confirmed Ricky Rubio will miss the rest of the 2021-22 season.

Rubio buckled as he planted in the lane during the fourth quarter of Tuesday's road game at the New Orleans Pelicans.

The 31-year-old, who has played a big role in the Cavaliers' strong start to the season in his first year with the team, clutched his left knee and was in clear distress. He had to be helped to his feet and to the locker room for further assessment.

Rubio was unable to put any weight on his left leg and further tests on Wednesday revealed the guard had torn his anterior cruciate ligament, ending his campaign early. 

With Darius Garland having entered the NBA's Health and Safety Protocols, Rubio started at point against the Pelicans and had 27 points while adding 13 rebounds and nine assists in what was a 104-108 defeat for Cleveland.

Rubio had enjoyed a fine start to life with the Cavs, having averaged a joint career-high 13.1 points per game through 34 appearances since his arrival from the Minnesota Timberwolves.

The Cavs sit fifth in the Eastern Conference, with a 20-14 record.
