Martin Truex Jr. suffered a scaphoid fracture and sprain of his right wrist in that multi-car accident in Bristol and will wear a cast at Atlanta and beyond.
According to a release from Michael Waltrip Racing, Truex has been cleared to race by NASCAR and isn't scheduled to miss any time behind the wheel. He's been fitted for a special cast to help him grip the wheel better. Per the release, MWR hasn't determined if a stand-by driver will be needed at Atlanta.
The scaphoid bone is one of the carpal bones in the wrist between the hand and forearm.
Treux was seen bracing his wrist from the in-car camera immediately after the accident Saturday night at Bristol. His car was swept into the wall from the high groove and the wheel viciously spun around on impact.
Truex is currently in 14th in the Sprint Cup standings with two races to go before the Chase. He occupies the first Wild Card berth as the three drivers in 11th-13th are winless.
