Cooley (upper body) won't play Saturday versus the Sharks and could be out longer than that, Ben Anderson of KSL Sports reports.
Cooley will miss a third straight game. If further evaluations of his injury give bad news, the 22-year-old could be placed on injured reserve in the coming days. Nick Schmaltz (lower body) is also ailing, so the Mammoth may want Cooley's roster spot for reinforcements soon.
