Busy day for Houston Texans running back Alfred Blue -- who found out his beloved Chevy Camaro somehow ended up in a Louisiana swamp Monday morning.
Here's the deal ... cops and a tow truck responded to Highway 90 in Des Allemands around 9 AM after a single car collision. One witness tells us, "The car was in the water."
Law enforcement tells TMZ Sports the NFL player is the owner of the car -- but he was NOT driving during the incident and was not present during the crash.
So, what happened?
