NBA spokesman Mike Bass made the announcement Tuesday in a statement, saying Roeser's leave of absence "will provide an opportunity for a new CEO to begin on a clean slate and for the team to stabilize under difficult circumstances."
The news comes just days after the NBA announced it would appoint a new CEO to run the Clippers.
Sterling was banned for life after a recording caught him making racist remarks. NBA Commissioner Adam Silver said he will try to force a sale of the Clippers and urged owners to vote in favor of forcing the sale.
Rochelle Sterling, Sterling's estranged wife and co-owner of the Clippers, said she fully supports the search for a new CEO.
"I spoke with Commissioner Adam Silver this week to tell him I fully supported his recent swift and decisive action," she said in a statement."
Roeser is one of the league's longest-tenured executives, having just completed his 30th season with the team.
The Clippers lead Oklahoma City 1-0 in the best-of-seven Western Conference semifinals.
