Crawford and Long both will be in uniform Friday night.
Crawford, acquired in a trade with Philadelphia in December, will make his Seattle debut at shortstop. He appeared in 72 games over the past two seasons with the Phillies. The 24-year-old has reached base safely in a Pacific Coast League-leading 31 consecutive games with Tacoma, including 27 games with at least one hit.
Moore was injured after being hit by a pitch Wednesday against the Yankees.
