Arena Football League:

In 2001, Jeff Foley published War on the Floor: An Average Guy Plays in the Arena Football League and Lives to Write About It. The book details a journalist's two preseasons (1999 and 2000) as an offensive specialist/writer with the now-defunct Albany Firebirds. The 5-foot-6 (170 cm), self-described "unathletic writer" played in three preseason games and had one catch for −2 yards.
