Earnhardt was scheduled to compete in Saturdayâs Xfinity Series at Mid-Ohio Sports Car Course in Joe Gibbs Racingâs No. 18 sponsored by iK9.
A spokesman for JGR told Motorsport.com that iK9 remained a sponsor of the organization and the team would announce a new driver for this weekendâs Mid-Ohio event âsoon.â
Earnhardt was scheduled to compete in the Xfinity race at Daytona earlier this month but the Xtreme Concepts team withdrew its No. 81 Toyota entry just days before the event.
The fourth generation racer has made seven starts in the Xfinity Series this year, splitting his time between the No. 81 XCI Racing Toyota and the No. 18 JGR Toyota. He scored a career-best result of third at Charlotte Motor Speedway in May and led 29 laps in the season-opener at Daytona.
He also made one Cup start with XCI Racing at Talladega in the spring, starting 33rd and finishing 22ndÂ after being caught up in a last-lap wreck.
