60 laps left Keslowski was in 2nd, Kenseth 4th... Keslowski ran Kenseth into the wall trying to block him (hence Kenseth finishing 19th)... then on a restart Keslowski was behind Hamlin and they were bumping around and Keslowski finished like 9th or 10th and went after Hamlin on cool down lap trying to spin him out. Keslowski then found Kenseth and banged into his side a few times. They run into Smoke and Smoke ends up taking the entire front end off of Keslowski. Kenseth went after Keslowski out of the car because he was upset with Keslowski hitting him at 50mph or so when Kenseth already had his safety equipment off (seatbelt, helmet, hans, etc).
Keslowski blamed it all on everyone else.
