Marc Staal said that there is “no comparison” between the concussion he suffered on Dec. 7 and the one he sustained in February of 2011 that ultimately sidelined him for the first 36 games of the 2011-12 season. “The last time, I played through a concussion for so long, the effects dragged on forever,” the Rangers’ alternate captain said Sunday morning. “This one is different. “From day-to-day afterward, I’ve felt better, quicker. There is no comparison.” Staal, symptom-free for at least the last several days, spoke in his team’s locker room at the practice facility before skating for the second straight day. The Rangers-Wild match at the Garden Sunday night will mark his seventh straight game out of the lineup since he left the ice immediately after taking a hit up high from the Devils’ Reid Boucher midway through the third period of the Dec. 7, 4-3 OT defeat at the Garden. “I had loud ringing in my ears and a headache right after, so I knew something was wrong,” Staal said. “Having come back too early the last time, I knew [the risks]. “If I hadn’t had that [prior experience] I might have gone back out, but now I’m a little more educated, so I stayed off.” That time, Staal missed three games in the immediate aftermath of the Feb. 22 blow he took from his brother, Eric, in Raleigh, and then missed two more approximately a month later, but then played the final eight games of the regular-season and all five games of his club’s first-round playoff defeat to the Caps. When Staal went out after sustaining that concussion, it marked the first game he had ever missed because of injury in his NHL career that began in 2007-08.
