Alfredsson did not join the Senators for their trip to New York and will not play in Game 5 of the Senators' Eastern Conference Quarterfinal series against the Rangers.
Alfredsson has not played since absorbing an elbow to the head from the Rangers forward Carl Hagelin during the second period of Game 2. Hagelin was suspended three games for the hit and is eligible to return to the lineup for Game 6 on Monday.
For our team, as a group, we've never been this far before, and so it's just more lessons learned, and sometimes you have to go to the school of hard knocks to find out what works and what doesn't. We've got a young group. They've played some unreal hockey here to get us this far, and we showed if we're not going to play the proper way, a really, really good hockey team is going to beat you, and that's what they did. It's a lesson learned.
