Former NBA Rookie of the Year Ja Morant has returned for the Memphis Grizzlies after more than three weeks out with a left knee sprain.

Morant, who was the second pick in the 2019 NBA Draft, was back in the Grizzlies' starting line-up for Monday's game against the Oklahoma City Thunder.

The young gun had not played since he hobbled off in their 132-100 loss to the Atlanta Hawks on November 26.

The 22-year-old had been averaging 24.1 points, 5.6 rebounds and 6.8 assists per game until the injury. He was shooting at 47.6 percent from the field.

The Grizzlies had remarkably held a 10-2 record in his absence, improving from 9-10 to 19-12 prior to the Thunder game.

In the early part of this year, Morant had been spoken about as a potential Most Improved Player candidate, despite already scoring 19.1 points per game last year – the 36th-most in the league.
