Modo was found as an abandoned babe at the gates of the Sigmarite temple in Bogenhafen. The priests kept him around, even as he grew and grew beyond their expectation. He was handy for helping with hard labor, and keeping rowdy Blood Bowl fans from storming the serenity of the temple. However, unbeknownst to the holy men, Modo dreamed of the gridiron. At the moment, he joins the team incognito.

Which is probably the reason why after each injury he is forced to miss the next game as he tries to hide his pastime from his benefactors. So far he's only managed to play every other game.
