Ellis is scheduled to have an MRI exam on his sore back Monday. He did not accompany the team to Miami, where the Warriors begin a five-game trip Tuesday. Ellis already missed a game last Saturday. His status for the rest of the trip will be determined later Monday or Tuesday.
The team says Biedrins, who has a sports hernia, will miss the entire trip. He is scheduled to be examined in Philadelphia next Monday by a specialist. He left Saturday's game against Detroit with the injury and did not return.
The Warriors have the third-worst record in the NBA at 17-41.
