The Lakers did not provide a timeline for his return. However, ESPN's Dave McMenamin reported that the team's medical staff will take their time with James' injury.

The Athletic's Shams Charania reported that the Lakers expect LeBron to miss “at least” one week.

This early in the season, the Lakers may very well take every precaution with the 36-year-old, who is averaging 24.8 points, 5.5 rebounds, and 7.0 assists, six games into his 19th NBA season.

LeBron aggravated the injury during the Lakers' win over the Houston Rockets on Tuesday. He could be seen stretching in the tunnel in the fourth quarter before returning to seal the win, scoring 10 straight points down the stretch. There was no mention of the injury afterward, though LeBron did have his midsection wrapped in ice.

James missed two games last week — including the first meeting with OKC — due to ankle soreness, for which he was listed as questionable in every game since.

Following Thursday's game vs. OKC, the Lakers (5-3) will visit the Portland Trail Blazers on Saturday, then host the Charlotte Hornets (Monday), Miami Heat (Wednesday), and Minnesota Timberwolves (Friday, Nov. 12).
