Brendan Shanahan doesn't remember the collision with Mike Knuble or the shift on which it occurred, and still suffers from vertigo. Doctors haven't cleared him for anything other than light stretching, but he believes he will return before the season ends. "I'm optimistic," Shanahan said. "I don't have any experience to draw from, but I've been very lucky in my career with injuries, especially concussions."
Dizzy spells, disorientation. Sense of spinning or feeling of disequilibrium. It is often accompanied by nausea and occasionally vomiting and is generally worsened by motion. Sometimes caused by blood vessel compression of balance nerves.
Shanahan is hall of fame don't you think. He may not be the fastest but he goes where the puck is going to be so he is a smart player and a good shot and i hope he would come back a leader for the Rangers and one of there better players and better players in the league.
