The upcoming 2016 North American League Championship Series Summer Promotion Tournament has been rescheduled for April 6, Riot Games announced Monday.

The tournament had previously been set to start on March 24 with an elimination round between last-place 2016 NA LCS Spring team, Team Dignitas, and the 2016 NA CS Spring runner-up, Team Dragon Knights. The tournament's structure will remain the same, with Dignitas and Team Dragon Knights first squaring off first for the chance to play in the qualifying double elimination bracket along with ninth-place LCS team Team Impulse, eighth-place LCS team Renegades and NA CS Spring champion Team Apex.

Riot Games cited work eligibility as the reason behind the move, stating that they wanted to give their two challenger teams ample opportunity to acquire the correct visas for their players in the upcoming Promotion Tournament.

“For the majority of the season, CS teams participate in an online tournament, and a relatively short one," Riot said in their press release. "We felt that it was a burden to ask CS teams to go through the legally unnecessary and expensive visa process on the chance that they might make CS playoffs, then might advance to Promotion, then might win a spot in the LCS.”

Further stating that the work eligibility legal and practical rules for the Championship and Challenger Series differed, Riot was approached by team owners worried that the work visa acquisitions required by LCS teams wouldn’t be applied to CS teams, placing the former at a disadvantage. Stressing that these CS teams have been operating under “good faith” from Riot, a level playing field for all teams was said to be the desired outcome.

Riot also stated that a new work eligibility ruleset is in the works for future Promotion Tournaments to hopefully eliminate any confusion.

No changes have been made to the European LCS Summer Promotion Tournament schedule, as all EU CS players have met the work eligibility requirements according to Riot.
