Murphy was having more tests done Tuesday and there's still a chance he joins the Coyotes during their road trip, Tippett said. Tippett adjusted his lines during the loss to the Penguins, moving Doan with Martinook and Crouse and having Perlini play with Hanzal and Vrbata. … Blashill moved Athanasiou between Nyquist and Vanek, with Sheahan dropping onto a line with Nielsen and Larkin. Sheahan is scoreless in 29 games this season. "Riley's a north-south player, and that's what we want on a line with Nielsen," Blashill said. "He's playing well enough to get points; he just needs a break or two." … Athanasiou is hoping to provide the speed that made Helm successful earlier this season with Nyquist and Vanek. "Those are two top-class movers of the puck and they can both finish, so I'm hoping I'll be able to open some things up for them," Athanasiou said.
