Canadian players Andy "Smoothie" Ta and Johnny "Altec" Ru are listed on Cloud9's roster on Riot's official lineup page as of Thursday morning, and will likely act as substitute players for the main roster as they compete for the organization's NA Challenger Series squad.

Cloud9 initially announced its Challenger team would be made up of Hai "Hai" Lam, Lee "Rush" Yoonjae, An "Balls" Le and Daerek "LemonNation" Hart. A subsequent report from ESPN's Jacob Wolf suggested Altec, the former AD carry for NRG eSports, would join as Cloud9 Challenger's ADC, and his appearance on the team's official roster appears to confirm this move.

This is the first news that Smoothie will play for Cloud9. He was most recently a support substitute for Team Liquid's ten-man roster. He played a single game during the NA LCS 2016 Spring Split, on Janna, and got a decent 2.25 KDA despite losing the game.

Both Smoothie and Altec are listed on Cloud9's NA LCS roster for the split, alongside the confirmed members of Cloud9's Challenger team. Cloud9 likely intends to use its Challenger players as subs during the LCS split, though it is possible that Smoothie or Altec could sub for the main lineup without playing in Challenger.

LemonNation is listed by Riot as a coach, and has filled that role for the team in previous splits.

Cloud9 full, ten-man roster looks as follows:

Name Pos Lineup Jung "Impact" Eon-yeong Top Starting William "Meteos" Hartman Jungle Starting Nicolaj "Jensen" Jensen Mid Starting Zachary "Sneaky" Scuderi AD carry Starting Michael "Bunny FuFuu" Kurylo Support Starting An "BalIs" Van Le Top Sub / Challenger Lee "Rush" Yoon-jae Jungle Sub / Challenger Johnny "Altec" Ru AD carry Sub / Challenger Hai "Hai" Lam Jungle Sub / Challenger Andy "Smoothie" Ta Support Sub / Challenger

Cloud9 Challenger's roster will not be officially listed until the Summer Qualifiers on May 25. Cloud9 has not yet qualified for the Challenger Series, but must first fight its way through the qualification bracket.
