Weger played safety for the Lions from 1967 to 1975, and with the Houston Oilers from 1976 to 1977. He was twice named honorable mention All-Pro by the Associated Press. He finished his career with 17 interceptions, six fumble recoveries and scored two defensive touchdowns.
He also played a small part as himself in the 1968 film Paper Lion.[2] He sang the unofficial BGSU Fight Song "Ay-Ziggy-Zoomba" in the film.
Weger is currently involved in real estate development. For a time he operated a golf driving range and recreation center on M-24 in Lake Orion, Michigan, which also served as a location for Detroit Lions special events.[citation needed].
Mike Weger was involved in land swap at M-24 and Scripps Road to clear cut and develop previously state owned land. The land swap was deemed controversial and took several years of fighting with local city officials to go through.[3]
