James sat out his fifth straight game, which the Lakers lost 119-112 to the New York Knicks, and has been ruled out for the Lakers' upcoming two-game road trip. The team said in a release Friday that James continues to receive daily treatment and will be re-evaluated in a week.
"We got to get him healthy," Lakers coach Luke Walton said at shootaround Friday. "We talk all year, we need everyone on our team. You don't want anyone to get hurt. That's how the NBA season plays out. We're down in bodies. It's gonna be a challenge, but our guys should be excited for that. We gotta find a way to keep playing at a high level and try to finish some of these games out."
James participated little in practice Tuesday but did get some shots up in front of Walton for the first time since being injured on Christmas against the Golden State Warriors.
Friday's loss dropped the Lakers to 1-4 without James since the injury.
James will also be sidelined Sunday at the Minnesota Timberwolves and Monday at the Dallas Mavericks. The Lakers' one-week time frame would also make James unlikely for a home game against the Detroit Pistons on Wednesday.
Sources previously told ESPN's Brian Windhorst and Adrian Wojnarowski that the team had been preparing for James to miss several games.
Walton said the Lakers' medical staff wanted Kuzma to rest at home rather than come to the game and sit in traffic and possibly agitate the injury.
Walton said he is hopeful that Kuzma might be able to join the Lakers on their upcoming two-game trip and possibly be available.
