Andy Dalton and the Cincinnati Bengals didn't flinch. No, all they had to do was bide their time and wait for the San Diego Chargers to cough up another fourth-quarter lead. Dalton scrambled up the middle for a 6-yard touchdown with 4:11 left for the go-ahead score, and the Bengals won their fourth straight game, 20-13 over the punchless San Diego Chargers on Sunday.
