New York Jets quarterback Aaron Rodgers reportedly suffered a strained calf, per Josina Anderson of CBS Sports.
Anderson noted the setback is "considered minor" and shouldn't sideline him for long.
Rodgers was traded to the Jets by the Green Bay Packers in April after 18 years with the franchise.
During his final season in Green Bay, the four-time MVP completed 64.6 percent of his passes for 3,695 yards and 26 touchdowns against 12 interceptions in 17 games. It wasn't his best season, and the Packers struggled as a whole, finishing with an 8-9 record.
