PITTSBURGH -- Green Bay Packers wide receiver Jordy Nelson left Sunday's exhibition game against Pittsburgh in the first quarter with a potentially serious left knee injury.
Nelson, who caught a career-high 98 passes in 2014 while making the Pro Bowl for the first time, fell to the ground when he tried to cut after making an 8-yard reception on Green Bay's opening drive.
Nelson appeared to have plenty of room to run when defensive back Antwon Blake slipped but instead tumbled to the turf. Nelson was able to gather himself and walk off the field but did not return.
