Connor Mosack will run the last three races of the NASCAR Xfinity Series season for Viking Motorsports, the team announced Oct. 13.
In driving the No. 99, he replaces Matt DiBenedetto, who has competed for the team since its inception.
“We’d like to thank Matt for his contributions throughout our inaugural season,” Jeremy Lange, Viking GM, said in a team release. “He played a meaningful role in establishing the foundation of this team, and we wish him the best.”
The release noted Viking has not yet finalized its lineup for the 2026 NASCAR O’Reilly Auto Parts Series season.
In 2025, DiBenedetto had one top five and top 10 with the team, a fifth-place result at Talladega Superspeedway.
Mosack has been full time in the NASCAR Craftsman Truck Series this year for McAnally-Hilgemann Racing, earning four top 10s in the No. 81. He also has one top five and top 10 in Xfinity this year with JR Motorsports.
