[1] For the 2018 season, the Arizona Rattlers, Cedar Rapids Titans, Green Bay Blizzard, Iowa Barnstormers, and Nebraska Danger had all committed to play.
On September 12, 2017, it was announced that the Bloomington Edge and West Michigan Ironmen had joined the IFL for the 2018 season.
[6] The CIF then retracted their lawsuit with the IFL but also removed the Storm and Nighthawks from their 2018 schedule.
A temporary injunction from participation was granted on January 31, 2018, with the court ruling determining that both teams had been offered bribes from the owner of the Arizona Rattlers to break their contracts with the CIF.
[10][11] The schedule was revised in February for the six participating teams stating the Edge and Ironmen were to return in 2019.
