The team is preparing to be without Schroder for 10 to 14 days, a source told ESPN.
Schroder sat out L.A.'s 121-114 loss to the Toronto Raptors on Sunday because of the protocols. It was the second COVID-19-related absence for the Lakers point guard. He missed four games in February because of a contact-tracing violation.
The Lakers have eight games remaining on their regular-season schedule and host the Denver Nuggets on Monday in the second leg of a back-to-back.
