Davis is available to play on Friday but isn't guaranteed to be in the rotation. He should not be rostered in fantasy leagues.
Davis isn't in the rotation when healthy, so his absence will not impact fantasy basketball. Leave him on the waiver wire.
Poole hasn't miss a game since late November, but there is a chance that he is sidelined against the Knicks. If that happens, Malcolm Brogdon will likely make a return to the starting unit, with Jared Butler and Johnny Davis potentially seeing some minutes off the bench. However, only Brogdon will play enough to make any impact in fantasy basketball.
