The Pacers will be without forwards Lance Stephenson and Danny Granger for Friday's home game against Portland.
Stephenson, who has four triple-doubles this season, injured his lower back in Indiana's 89-85 win over Atlanta on Tuesday.
Stephenson, who is averaging 14.1 points and 7.2 rebounds, has started every game he's played in this season. He missed the game against Atlanta where Granger started in his place.
Granger played in 23 games this season after returning from a calf injury in December. He has not started since Jan. 8.
