The North American player will be filling in for Fernando "fer" Alvarenga, who is ruled out of the event as he will undergo surgery to fix an ear problem.
BLAST Pro Series Lisbon will be held at Altice Arena from December 14-15, with $250,000 in prize money. It is believed that MIBR turned to swag as the event will clash with both PLG Grand Slam - where INTZ will be in attendance - and the closed qualifier for the Americas Minor, in which the former iBUYPOWER member cannot compete due to being banned from all Valve-sponsored tournaments.
swag recently played at the WESG 2018 US Regional Finals, where Swole Patrol finished runners-up to Singularity. Before that, he had attended EPICENTER 2018 - his first Big Event since DreamHack Winter 2014, helping his team to reach the main tournament before they lost to Liquid and NiP in the group stage.
"This will be a great opportunity for me, and I look forward to playing alongside such legendary names," swag said.
"I think it will be a great experience, playing on stage is a thing that I miss. I am super excited, and I will do everything I can to prepare and try to get some wins for MIBR and the fans."
MIBR will attend the event with:
Janko "YNk" Paunović (coach)
