Center Evgeni Malkin tested his injured shoulder during an optional practice Wednesday morning. During puck possession drills in which he circled from behind the cage to the half-walls and back, Malkin was bumped by Penguins defensemen. That marked his first contact since he was injured at Toronto by a hit from Maple Leafs winger James van Riemsdyk on March 9. Malkin described himself Wednesday as “not 100 percent” and attempted to lower expectations for a return Friday at the New York Islanders. “Of course, yes, because (I'm) close,” Malkin said. “I (will) try to play Friday, but it's hard to say now because it's just (a) couple days more. We'll see.” Malkin has missed the last six games. He has played in only three of the Penguins' previous 13 games. They are 11-2-0 over that stretch but only 7 for 31 (22.6 percent) on the power play without Malkin in the lineup. Malkin is considered day to day, coach Dan Bylsma said.
