08:24 AM ET 12.16 | Finally, a bit of good news sharing a headline with "concussion." Rangers defenseman Marc Staal still doesn't know when he's going to play for the first time this season, but his progress in recovering from a concussion continued during Thursday's morning skate. "The past few days have been the hardest I've skated in a really long time," Staal said following the morning skate at the Scottrade Center before the Rangers [opened] a three-game road trip against the Blues on Thursday. "The last week has gone really well. I've been ramping it up a little more." Staal has missed the entire start of the season after suffering a summertime setback related to a February injury, and knows he shouldn't look forward too much.
