Walker has been out since suffering a concussion during a March 12 loss to the Knicks. His absence has freed up rotation minutes for Duop Reath, who has not done enough to merit being rostered. However, with Donovan Clingan (illness) also questionable for Sunday’s game, Reath may have added value on Sunday.

This will be a fourth-straight absence for Walker since he took an elbow to the jaw courtesy of Karl-Anthony Towns last week. Duop Reath will continue to fill out the backup center minutes behind Donovan Clingan, where he has scored in double figures in two straight games.

Walker remains in the league’s concussion protocol and will not be available for Sunday’s game. His absence means more rotation minutes for Duop Reath, especially if Robert Williams remains out with a knee injury. If Williams can play, there wouldn’t be much to gain from streaming Reath in most leagues.

Walker took a Karl-Anthony Towns elbow to the jaw during Wednesday’s loss to the Knicks and did not return to the game. Blazers coach Chauncey Billups said on Friday that Walker has entered concussion protocol, so he’s unlikely to be available for Sunday’s game against the Raptors.
