Los Angeles, California - Four-time NBA MVP LeBron James has entered the league's health and safety protocols after testing positive for Covid-19.

The 36-year-old, who is reportedly asymptomatic, was set to line up for the Los Angeles Lakers against the Sacramento Kings on Tuesday but was ruled out ahead of tip-off.

James is likely to be out for several games, having already missed 11 of the Lakers' 22 games this season with ankle and abdominal injuries, along with a one-game suspension for clashing with the Pistons' Isaiah Stewart.

The NBA mandates a minimum of 10 days of isolation away from a player's team if they have tested positive to Covid-19, before mandatory cardiac screening and reconditioning to be cleared to return. James confirmed in September that he has been vaccinated from Covid-19.

The Lakers, who are 11-11 across the 2021-22 NBA season, are 4-7 without James in the team this campaign.

James is averaging 25.8 points, 5.2 rebounds, and 6.8 assists per game from 11 games this season.
