John Murphy: 3rd down and long. Lamar Jackson in the shotgun (because that's all he knew in Petrino's offense). Here's the snap. DJ Chark getting separation, but I don't think Jackson sees him. Pressure coming and Jackson will take off. He's at the 30, the 35, the 40 trying to get out of bounds and OH! Jackson took a vicious hit to the knee from the safety and he is down!
