Former NFL linebacker Bill Romanowski has signed on as a minority-owner of Swan Racing in the Sprint Cup Series, the team announced on Thursday.

Romanowski joined forces with upstart team owner Brandon Davis, who is leading Swan into its inaugural full season in NASCAR's premier series. The team will make its debut in the Feb. 24 Daytona 500. Romanowski's health supplement company, Nutrition53, will serve as primary sponsor of Swan's No. 30 Toyota, driven by David Stremme, for 10 of 36 Sprint Cup races during the 2013 season. Nutrition53 will have an associate sponsor position on the car for the other 26 events.

"I am thrilled to jump into the NASCAR world as a part owner and as a sponsor," Romanowski said in a team statement. "Brandon has a vision for how to build a championship contender, and I'm eager to be part of it."

Romanowski played for the San Francisco 49ers, Philadelphia Eagles, Denver Broncos and Oakland Raiders during his 16-year career in the NFL. He started in 243 consecutive games, appeared in five Super Bowls and was selected to the Pro Bowl twice.

"Bill Romanowski understands what it takes to win, which makes him a perfect fit at Swan Racing," Davis said. "Bill is the only linebacker to start in five Super Bowls, and he did it playing for four different teams. His leadership skills and approach to successful competition will help Swan Racing become a championship contender."

Two-time Daytona 500 winner Michael Waltrip is scheduled to drive the No. 30 car in next month's season-opening race at Daytona International Speedway.
