According to the LCS competitive ruling on Echo Fox multiple teams were asking questions about the eligibility of multiple foreign players now in the league. So in an effort to appease those allegations the LCS had teams submit full work eligibility documents for all of their players by Tuesday, January 19.
Apparently some players on Echo Fox’s team are not technically work eligible as they did not manage to field an eligible team for this week’s match against NRG and are now forced to forfeit. They can still play tomorrow against Team Liquid, assuming they get a roster submitted in time.
So, NRG are still undefeated at 3-0 and Echo Fox are now 1-2.
