Jacksonville Jaguars receiver Justin Blackmon was escorted from the field following a heated argument with Miami Dolphins cornerback Nolan Carroll in the second quarter.
Blackmon sat out Friday night’s 27-3 exhibition loss to the Dolphins while recovering from groin surgery, but he was on the sideline in street clothes when he started jawing with Carroll. It was unclear who or what prompted the verbal tiff.
The exchange intensified to the point where Jaguars coach Gus Bradley got involved.
Running back Maurice Jones-Drew stepped in, calmed Blackmon down, and escorted him to the locker room.
Blackmon returned to the sideline to start the second half. Blackmon is suspended for the first four games of the regular season for violating the league’s substance-abuse policy. Full story for BostonGlobe.com subscribers.
