Just after the Bengals got on the board with a 4-yard touchdown pass to Jermaine Gresham, they suffered a little setback. Linebacker Rey Maualuga went to tackle Ryan Mathews, his left knee buckled as he stood up and he immediately felt discomfort. He hobbled off the field, but you can tell he was hurting for sure.
