Portland Trail Blazers guard CJ McCollum will not play in his team's against the Oklahoma City Thunder on Saturday due to a left ankle sprain, according to Jamie Goldberg of The Oregonian.

McCollum suffered the injury during the second quarter of the Blazers' loss to the Dallas Mavericks on Friday night and did not return. He scored four points in 11 minutes before exiting.

In 42 games this season, McCollum is averaging 21.5 points, four rebounds and 3.8 assists over 35.6 minutes per game while shooting 45.3 percent from the floor, 37.8 percent from three-point range and 78.9 percent from the free-throw line.

The 28-year-old, who played his collegiate basketball at Lehigh University, was originally selected by Portland with the 10th overall pick of the 2013 NBA Draft.

He received only scarce playing time during his rookie campaign, appearing in 38 contests and recording 5.3 points across 12.5 minutes a night.

The following season, McCollum began to develop into a more regular member of the rotation, participating in 62 games and registering 6.8 points through 15.7 minutes per game, and in 2015-16, McCollum broke out, starting all 80 games in which he played and posting 20.8 points, 4.3 assists, 3.2 rebounds and 1.2 steals over 34.8 minutes a night while making 44.8 percent of his field-goal attempts, 41.7 percent of his long-distance tries and 82.7 percent of his foul shots.

Since then, CJ McCollum has averaged over 20 points per game in every season, with his high-water mark coming during the 2016-17 campaign when he tallied 23 points per game while also shooting a league-best 91.2 percent from the charity stripe.

The Blazers have been one of the NBA's most disappointing teams this year and are just 18-25.
