Fred Jackson lied face-first in front of his own bench his knee having bent awkwardly as he was tackled near the sideline. The 60592 fans who had just settled into Sun Life Stadium for the Buffalo Bills' 23-21 victory against the Miami Dolphins on Sunday all had the same reaction: a collective gasp as the video board played a replay of the injury. While on the ground the 32-year old team captain was quickly surrounded by medical staff fellow running backs C.J. Spiller and Tashard Choice and head coach Doug Marrone. "I was scared" Marrone said. "I saw it happen. He went down in a quick movement. At first I was concerned." The Bills were concerned enough to bring out the cart for Jackson but after a few moments Jackson was able to get to his feet and return to the bench with the cart waved off. Jackson who said he aggravated a sprained MCL in his left knee on the play was back on the field for the next drive later capping it off with a 3-yard touchdown. "He's a legend. He's a real life legend. I don't even know what to say" receiver Stevie Johnson said. "He got injured came back. His leg was messed up and he still was running for first downs and touchdowns." One of those first downs was a key third-and-4 run late in the fourth quarter extending a Bills drive to set-up a go-ahead field goal. "We needed it" he said. "We had the opportunity to ice the game. You play for those types of moments and coach called my number. It was a great team effort on the offensive side of the ball."
