This game might not turn out as wild as the teams’ last meeting three years ago, when the Bolts rallied with 42 points in the second-half, but you never know. San Diego has won eight straight games to take sole possession of the AFC?West and has not lost a game in December since 2006. The Chargers have an edge in the passing game while Cincinnati has the edge on the ground, unless LaDainian Tomlinson pulls through with a solid effort. Look for an entertaining contest with turnovers possibly being the key to victory. All-time series: Chargers lead 18-10. Last meeting: San Diego won 49-41 at Cincinnati in 2006.
