The injury occurred in the club’s preseason opener vs. Chicago, the club said.
Zordich, 23, is an undrafted free agent from Penn State. He signed with the Panthers in May after rushing for a career-best 301 yards for the Nittany Lions in 2012. His father, Mike, had a 12-season NFL career as a defensive back (1987-1998).
With Zordich injured, starter Mike Tolbert is the only healthy fullback on the Panthers’ roster.
