According to Kevin Weekes, the two sides found a resolution. Today, Kolosov made the trip to Philadelphia and is officially playing with the team at training camp, where he will get preseason action.
It was then added by Elliotte Friedman that Kolosov just wants a fair chance. However, the Flyers did note that if things don't work out, Kolosov can go back to the KHL. So needless to say, it seems like everyone is getting what they want in the end.
