Kyle Larson isn't staying put very long.
Chip Ganassi Racing with Felix Sabates will move the 20-year-old upstart to the NASCAR Sprint Cup Series fulltime in 2014, multiple sources confirmed Tuesday to The Observer and ThatsRacin.com.
An official news conference to introduce the team's new driver is scheduled Friday at Atlanta Motor Speedway.
Reached by phone on Tuesday evening, a team spokesman declined comment.
Larson and team members of the Ganassi organization were notified of the decision this week, sources said. Larson will replace Juan Pablo Montoya in the No. 42 Chevrolet.
Larson is in his first full season in the Nationwide Series, running with Turner Scott Motorsports. He has yet to win in Nationwide but is eighth in the series standings and has finished second twice this season.
The native of Elk Grove, Calif., earned his first Truck series victory earlier this season at Rockingham, N.C., and won the 2012 NASCAR K&N Pro Series East championship.
As a teenager, Larson raced open-wheel cars, including USAC midget, Silver Crown and sprint cars. He also raced World of Outlaws sprint cars.
