VG.CyberZen and Bravado Gaming will be unable to play in the ESEA Season 22 Global Challenge due to visa issues preventing players forgetting to Poland, according to a report by HLTV's Milan "Striker" Švejda.

Bravado player Robby "bLacKpoisoN" Da Loca told HLTV that the team has been working on securing visas since the tournament was announced, but have been unable to get proper documents. Bravado Gaming is based in South Africa.

HLTV also wrote that CyberZen, a Chinese team, has been facing similar visa issues, though did not cite any sources.

The teams will be replaced by German team ALTERNATE aTTaX and Swedish team Crowns Esports Club, formerly known as Publicir.se, who signed AK-47's roster earlier today.

The rest of the teams attending the Global Challenge tournament are ENCE eSports, Echo Fox, Mortal Kombat, Chiefs eSports Club, g3nerationX and Pnda Gaming.

The ESEA Season 22 Global Challenge runs from Aug. 27-28 in Katowice, Poland and features a $50,000 prize pool.
