The one thing Ottawa Senators fans are anxious to find out is if Erik Karlsson will be suiting up for the Sens on opening night against the Capitals on October 5th.
Karlsson has been practicing with the team, but he's been wearing the blue non-contact jersey.
On Saturday, however, Karlsson practiced in a green jersey and we're really not sure what that means.

At this point, we can't say with certainty that any of those answers to what the green jersey means are wrong.
We can, however, ask you to give us some other suggestions as to what the colour change might mean by tweeting us @BarDown.
