The Memphis Grizzlies have demoted Chris Wallace and John Hollinger while elevating Jason Wexler to president.

Wallace and Hollinger will assume scouting and senior advisory roles. Wallace joined the Grizzlies in 2007.

Wexler will oversee basketball and business operations.

The franchise is planning to add experienced front-office executives to the organization.

"In order to put our team on the path to sustainable success, it was necessary to change our approach to basketball operations," team chairman Robert Pera said in a statement. "I look forward to a re-energized front office and fresh approach to Memphis Grizzlies basketball under new leadership, while retaining the identity and values that have distinguished our team."
