The UFC’s fourth event in Sweden will be its biggest yet as Stockholm’s Tele2Arena plays host to UFC on FOX 14, the second stadium show in company history, on Saturday.

UFC 129 in April 2011 was the first stadium even. More than 55,000 fans filled Toronto’s Rogers Centre. UFC on FOX 14 won’t top that attendance mark, but more than 20,000 fans are expected to fill the European venue.

Stockholm native Alexander Gustafsson (16-2 MMA, 8-2 UFC) is the main attraction for locals as he meets Anthony Johnson (18-4 MMA, 9-4 UFC) in the five-round light-heavyweight headliner.

The stakes don’t get much higher than this fight between “The Mauler” and “Rumble.” The winner earns No. 1 contender status in the 205-pound division and will challenge champion Jon Jones (21-1 MMA, 15-1 UFC) for the title this year.
