Washe was summoned from AHL San Diego on Wednesday.
Petr Mrazek (lower body) was put on injured reserve in a corresponding move. Washe has 13 goals and 25 points in 30 outings with San Diego in 2025-26. The 24-year-old hasn't played in the NHL yet this season, but he had no points, two shots and four hits across two regular-season appearances with Anaheim in 2024-25.
