AJ Allmendinger will return to the NASCAR Sprint Cup to rejoin Phoenix Racing in this weekend's Phoenix round.
Although Allmendinger looks increasingly likely to contest at least a handful of IndyCar races this season for former NASCAR employer Penske, he will replace Regan Smith in James Finch's Cup squad in Arizona.
"This will be good. It's been a few months since I've been in a stock car," said Allmendinger.
"I haven't been in one of the Gen 6 cars yet, so I think it will take a little time to get acclimatised to it."
Phoenix finished seventh in last weekend's Daytona 500 with Smith.
