CHARLOTTE, N.C. (AP) Panthers middle linebacker Luke Kuechly returned to practice for the first time since suffering a concussion in the Carolina's season-opening win against the Jacksonville Jaguars.

The four-year pro spent four weeks in the NFL's concussion protocol and missed three games before being cleared to return. The Panthers had a bye last week and travel to play Seattle on Sunday.

Kuechly, wearing pads and a helmet, was first in line during individual drills on Tuesday, hitting the blocking sleds seemingly as hard as he could.
