William "Meteos" Hartman was "traded from C9 to P1 and is now an active member of P1's starting roster," a representative for Riot Games told theScore esports.

On Thursday, Phoenix1's announced that Meteos "has graciously agreed to sub in for our team on extremely short notice" and will replace starting jungler Rami "Inori" Charagh in the team's Week 5 matches against Cloud9 and Team EnVyUs. The organization said that Inori needed to return home "to take care of a personal matter."

Riot Games esports media relations lead Alex Rubens confirmed to theScore esports in an email that Meteos had been acquired by P1 in exchange for cash, stating that "they purchased/acquired the contract from C9." Section 4.2.4.1 of Riot's 2017 NA LCS rules states that "Players may be traded from one team to another in exchange for a payment of cash or other consideration, so long as such transaction does not violate any other Rule(s)."

Phoenix1 did not immediately respond to a request for comment. Meteos now appears on Phoenix1's roster in the official League of Legends esports league-recognized contract database.

It's possible that Meteos could be moved to a substitute position after Inori returns. What cannot happen, as per section 4.1.6 of Riot's 2017 NA LCS rules, is a return to Cloud9 for three weeks:

Any player who leaves or is removed from an LCS Roster (for any reason) may not re-join that LCS Roster as a result of a later trade, free agent signing, or any other type of transaction until a minimum of at least three game (3) weeks has elapsed following the effective date of the transaction that resulted in their most recent removal from the Active Roster unless granted a hardship exemption at league discretion. A game week is defined as a week in which LCS matches are being played.

With P1 set to battle C9 in one of their two Week 5 matches, it was unclear if a loaned player could indeed play against their current roster. But with a trade now confirmed by Riot, the members of Cloud9 constitute former teammates to Meteos instead.
