Henrik Zetterberg was on the ice for an hour with his Red Wings teammates Sunday, another encouraging sign as he recovers from a knee injury. Zetterberg won't play tonight in Game 3 against Phoenix and isn't close to returning. His injury, a second-degree medial collateral ligament sprain, generally takes three weeks to heal. Zetterberg was hurt April 6. He began skating last week and has tried to add more work every day. "Feels better than yesterday," Zetterberg said Sunday. "I don't know if I did that much stuff, I'm not really in the battling drills, so there's not that much to do. But it's fun to be out there. Step by step. I feel a little better, and as long as the progress keeps going that way, I'm happy." Zetterberg had a little scare Saturday when he first got on the ice and felt a twinge in his knee, but he returned to skate for 30 minutes.
