Fresh off the Alexei Kolosov news, Ivan Fedotov might be clear to join the Flyers:

You might remember Fedotov was the Flyers prospect that was allegedly poisoned a couple years back and detained in Russia. At that point, there was a lot of Cold War energy in the air between the U.S. and Russia as the Ukraine conflict continued. I guess things have settled down, because he appears to be a free man.

NHL Insider Elliotte Friedman thinks this can actually happen:

This is HUGE! Felix Sandstrom stinks and Sam Ersson is going to die of exhaustion if he has to be in net for every game the rest of the season. Feddy Wap and Coca Kolosov are coming over to save the Flyers season.
