Earnhardt to miss 2+ more races because of concussion

Dale Earnhardt Jr. will miss at least two more races while he recovers from a concussion.

Earnhardt, who skipped the last three races, will sit out at Watkins Glen International on Sunday and at Bristol Motor Speedway on Aug. 20. Four-time series champion Jeff Gordon will replace Earnhardt behind the wheel in the No. 88 Chevrolet for Hendrick Motorsports.

The team made the announcement Monday, saying Earnhardt hasn't been cleared to race.

Earnhardt underwent further evaluation Monday at the University of Pittsburgh Medical Center Sports Medicine Concussion Program. The driver said on his weekly podcast that he continues to experience issues with balance and gaze stabilization.

Gordon subbed for Earnhardt at Indianapolis and Pocono, finishing 13th and 27th. His next start will be the 800th of his Cup career.
