Joining Benn on the back end will be Calen Addison and 2021 first-round pick Carson Lambos, two of the team's top defensive prospects.
Benn opened camp on the club's third defensive pairing with Dmitry Kulikov and is locked in a battle with Addison and Jon Merrill for a spot in the Opening Night lineup.
The Wild lineup will also have plenty of expected regulars from the Iowa Wild, including Dominic Turgeon, Joe Hicketts, Joseph Cramarossa, Dakota Mermis, Damien Giroux and Will Bitten.
Defensemen Ryan O'Rourke and Daemon Hunt, as well as forward Pavel Novak are other 2020 draft picks who will make their exhibition debuts in Minnesota sweaters on Saturday.
Kahkonen will draw the start. He went 16-8-0 in 24 games (23 starts) last season, with a .902 save percentage and a 2.88 goals-against average. Kahkonen allowed 16 goals in two starts at Enterprise Center, so Saturday's game could help the second-year netminder exorcise some demons in that building.
Hammond hasn't seen regular season or playoff action in the NHL since the 2017-18 season, but served as the Wild's taxi squad goaltender last season. He was one of the top goaltenders in the AHL in both 2018-19 and 2019-20.
The game Saturday marks the Wild's firs foray into the preseason. Minnesota will play at Colorado on Thursday before returning home for three consecutive exhibition contests at Xcel Energy Center: Oct. 4 against Colorado, Oct. 6 versus St. Louis and Oct. 7 against Chicago.
The WIld concludes the exhibition campaign at the United Center against the Blackhawks on Oct. 9 before opening the regular season six nights later against the Anaheim Ducks on Oct. 15 at the Honda Center.
