Cartion Landon Cassill is toast
Lap 246 — Kyle Busch, running 14th, is the first of a handful of cars to pit under the caution.
Lap 244 — YELLOW FLAG NO. 6: Landon Cassill has blown an engine.
Lap 242 — Tony Stewart is built his lead over Brad Keselowski to just over 1.1 seconds. Coming off Turn 2, Dale Earnhardt Jr. makes contact with the rear of Mark Martin’s car. That causes Martin to tap the backstretch wall.
