Seahawks joint practice Thursday, including altercations between Zach Tom and Seattle players Ernest Jones IV and Devon Witherspoon.

Teams’ win-loss records aren’t even on the line yet, and fights are already breaking out this fall. On Thursday, a brawl erupted between the Green Bay Packers and Seattle Seahawks at a joint practice.

The day began with Seahawks players taking part in one of the NFL’s unique traditions, riding bikes from the locker room at Lambeau Field to the practice fields a quarter-mile or so away.
