from Dana Wakiji of DetroitRedWings.com,
Thomas Vanek was about to go on the ice for the morning skate but returned to the dressing room.
Blashill said Vanek would miss the Sharks game with a mid-body injury.
He also said rookie Michael Rasmussen remains out tonight.
However, veteran defenseman Jonathan Ericsson will return to the lineup after missing five games with a lower-body injury.
"Johnny feels pretty good," Blashill said. "I think his wind is the only thing that's not quite there, but his legs have felt pretty good, he's been able to skate a decent amount, he feels like he's totally ready to go.
