Swan Racing's future is on the rocks and the two-car team is reviewing its ability to compete in NASCAR.
Cole Whitt drives the No. 26 Toyota Camry and Parker Kligerman drives the No. 30 Toyota Camry for Swan in the Sprint Cup series.
Swan Racing is owned by Brandon Davis, the CEO of independent oil and gas company Swan Energy.
The team says in a statement Thursday it has been unable to secure the sponsorship needed to effectively operate the team. Swan adds it is "exploring every available option."
Davis has been aggressively transforming the organization he purchased in late 2012. A former start-and-park team, he set a goal of racing in every event. Then he signed former NFL linebacker Bill Romanowski as an investor and rapper 50 Cent used his SMS Audio line to partner with the team.
