Career
Franck made his professional debuts with SV Waldhof Mannheim on 12 May 1989 at the age of 18, playing 12 minutes in a 3–4 home loss against VfB Stuttgart, with the club then in the Bundesliga (it would be his only appearance of the season, and he played in 18 matches more the following campaign, which ended in relegation). Franck subsequently signed for 1. Football Club Kaiserslautern, winning consecutive league titles, one in each of the two major levels.
In the 1997-1998 topflight campaign, however, he appeared in no matches, due to injuries.
In the following years, he appeared with three teams in different divisions – including former side Waldhof – with no impact whatsoever (he was also sidelined for the entirety of 1998-1999), finally retiring from football at the age of 33.
