The San Diego Chargers' secondary might look different Sunday when they take on the Cincinnati Bengals.
Coach Mike McCoy and defensive coordinator John Pagano say there's a competition among the defensive backs after the Chargers allowed Alex Smith to throw for 294 yards and three touchdowns in San Diego's 41-38 win Sunday.
Cornerback Derek Cox was benched for the third time in four games, leading McCoy to say there would be a competition for jobs.
Cox was one of the team's key free-agent signings in the offseason.
Says Pagano: "There were positives in that Kansas City game, but our bad is bad."
San Diego (5-6) hosts AFC North-leading Cincinnati (7-4) on Sunday.
