The Michael Waltrip Racing driver was fitted with a cast that will allow him to grip the steering wheel better. He is not expected to miss any time behind the wheel, and he has been cleared to race in the AdvoCare 500 at Atlanta Motor Speedway.
On lap 448 of the Food City 500, Truex Jr was racing with Kevin Harvick and Denny Hamlin, when Hamlin and Harvick got together sending the three into Ryan Newman and the outside retaining wall.
Truex’s car then slid down the track and made contact with the No. 30 of David Stremme and the No. 32 of Ken Schrader.
Truex immediately grabbed his wrist, video replays show.
Truex Jr joins Denny Hamlin and Tony Stewart on a growing list of injured drivers this season. Stewart is out for the remainder of the 2013 Sprint Cup season  after breaking his leg  racing sprint cars. And, Hamlin missed six races  after fracturing a vertebra during the Kobalt Tools 400 at Las Vegas Motor Speedway.
