Tennessee ThunderCats

The Johnstown Riverhawks was a professional indoor American football team based out of Johnstown, Pennsylvania. They were a charter member of the American Indoor Football Association (AIFA). They played their home games at Cambria County War Memorial Arena.

The Riverhawks began play in 1999 as the Topeka Knights of the Indoor Football League. They missed the playoffs in their inaugural season, finishing third in the Northern Division at 6-6. During the second season, the team changed ownership and became the Topeka Kings. The team finished with a much better record, going 10-4 and winning the Western Conference, Southern Division championship. In the playoffs, they defeated the Black Hills Machine in the quarterfinal round before losing to the Bismarck Blaze in the semifinals.

After the season, they moved to Knoxville, Tennessee became the Tennessee ThunderCats, and moved to the Indoor Professional Football League. They would impressively win the league championship in their first year. After the IPFL folded, the ThunderCats moved to the NIFL. During their tenure in the league, they had decent success in 2002, but considerably less success as the Tennessee Riverhawks in 2003.

In 2004, while they were the Greenville Riverhawks, their ownership folded after three games. The team itself moved to Lancaster, Pennsylvania and played their remaining games. Then, they were re-founded by Andrew Haines, owner of the Atlantic Indoor Football League. The team was purchased by Brian Schwelling of Atlanta, Georgia in February 2005. Schwelling operated the team successfully until September of that same year when it was sold to Michael Dawson. Schwelling was successful in bringing the Riverhawks to the semifinal game in the team's inaugural season.
