NASCAR Sprint Cup rookie Ryan Truex hit the Turn 2 wall hard Saturday morning in the day's opening practice session at Michigan International Speedway.
Running eight laps in the early morning session, Truex lost the back end of his No. 83 Toyota. The car corrected and shot head-on into the outside wall. Per NASCAR's new rule, Truex remained in the car until NASCAR and safety officials arrived on site, and then walked away under his own power.
According to a BK Racing official, Truex was complaining of a headache and shoulder pain and was transported to a local hospital for further evaluation. Truex broke his collarbone in 2013 while riding a motorcycle.
After Saturday's NASCAR Camping World Truck Series race, BK Racing officials said Truex underwent CT scans of his head, neck, chest and abdomen, all of which were negative.
Truex was diagnosed with a concussion and will sit out Sunday's Pure Michgan 400, and "follow the NASCAR guidelines to return to racing."
The team announced JJ Yeley would fill in for the rookie driver.
Prior to the wreck, Truex had posted the 33rd fastest time with a lap at 200.061 mph. He is scheduled to start Sunday's race 31st.
In the day's opening practice, Stewart-Haas Racing's Kevin Harvick and Kurt Busch swept the top two spots in the day's first practice, followed by pole sitter Jeff Gordon, Dale Earnhardt Jr. and Marcos Ambrose.
During final practice, Camping World Truck Series regulars Matt Crafton and Johnny Sauter met with the team, but neither made a lap in the backup car. After Saturday's race -- in which Sauter and Crafton finished first and second -- Crafton indicated neither driver fit in Truex's seat and with championship implications on the line there was to much to risk.
