Youngblood has been ruled out for Wednesday's game against the Thunder due to a right foot bruise.
Youngblood came down awkwardly following a fastbreak layup attempt at the start of the fourth quarter during Tuesday's win over the Thunder and didn't return. He's recently carved out a role in Portland, averaging 14.8 minutes per game over the past five appearances, so in his absence, Sidy Cissoko and Scoot Henderson are candidates for increased roles.
