SAN DIEGO (AP) San Diego Chargers guard D.J. Fluker says his most recent concussion was the scariest of the four he's had in his three NFL seasons.

Fluker was injured late in a 33-3 loss to the Kansas City Chiefs on Nov. 22 and missed the next two games.

He returned to practice on Wednesday as the Chargers (3-9) prepared for Sunday's game at Kansas City (7-5).

Fluker says his entire body tingled and his focus went in and out for a few plays.

Says Fluker: ''I can play through any injury, hurt or whatever, but killing my brain is a whole different subject.''

Fluker had suffered a concussion the Wednesday before the KC game. He didn't practice the following two days but was cleared to play.
