Tonight @coLroca will be standing in for our CS:GO team in @FACEIT's ECS 3.5 million dollar league qualifier against KKona. Gl Hf :) — Carey Kertenian (@careyfrozt) April 7, 2016

roca will be playing instead of Trey "tck" Martin. It is unclear why tck can't play in the match.

Echo Fox is currently in first place in Group A of the ECS North American qualifier, with a 2-0-0 record, while KKona is in last, with 0-0-1 after their loss to Without a Roof.

This is Echo Fox's last match of the Group Stage. If they win, they are guaranteed to make it to the playoffs bracket, where they will play either Selfless Gaming or Splyce for a spot in the ECS North American league.

ECS was announced on Wednesday and is a 20-team CS:GO league with a $3.5 million prize pool. FACEIT and Twitch also announced in the initial press release that the league is offering teams co-ownership.
