Greg Biffle...Ouchie!

Greg Biffle will not compete in Saturday's Nationwide Series race at Bristol Motor Speedway after suffering a rib injury from a boating accident earlier in the week.Biffle, a Sprint Cup Series regular, said he slipped and fell while attempting to jump from the dock to the boat. He said the slip resulted in his right side striking the edge of the boat. Biffle was boating with friends near his home in Charlotte, North Carolina.

As a precaution, Biffle opted not to drive in the 300-lap race at Bristol, with Roush Fenway Racing teammate Matt Kenseth taking his place. Biffle and Kenseth have agreed to swap Nationwide races, with Biffle substituting for Kenseth in the No.16 Ford in an upcoming event this season.

Biffle, who is currently 10th in Sprint Cup points, is expected to compete in Sunday's Food City 500 at Bristol.

Greg!!! I dont want to be a mom here, but please can you go boating in December so you don't hurt yourself during the regular season!! Our thoughts are with you!
