Will Derek Cox return to starting lineup?

SAN DIEGO -- Cornerback Derek Cox's time on the sideline as a reserve could be a short stint.

After being benched in the second half of San Diego's 30-24 overtime loss at Washington, San Diego coach Mike McCoy said Cox had a conversation with defensive coordinator John Pagano on the plane ride home about why he was taken out of the game.

“Yeah, I talked to him on the plane,” Cox said. “He just told me that it was his decision, and something that he pretty much just did in the heat of the battle. And he told me not to worry about it at all.”

So will Cox be returning to the starting lineup this week?

“It's probably best to ask him [Pagano] and see what he says,” Cox said.

Cox, who signed a four-year, $20 million deal in free agency with the Chargers after playing his first four seasons in Jacksonville, struggled at times covering receivers deep during the first half of the season.

In the Washington game, Cox was replaced by Johnny Patrick in the third quarter after giving up a 38-yard reception to Washington receiver Pierre Garcon.

“If there is something we are going to change from week-to-week because we think it's the best opportunity or because something happens in a certain game, we're going to make changes,” McCoy said. “Players are not always going to agree with what you do and how you do things, but that's our job as coaches -- do what we think is best for the team."
