5-Hour Energy can remain as sponsor of Furniture Row Racing – and only of Furniture Row Racing – as long as Monster Energy is sponsor of the NASCAR Cup Series. It cannot change teams and cannot follow driver Erik Jones if he leaves as part of the grandfather clause implemented by NASCAR in light of Monster's exclusivity provision as part of the sponsorship. The reason 5-Hour can stay is because its contract with Furniture Row – signed before the Monster deal was done with NASCAR – has option clauses for an extension, and NASCAR cannot bar those clauses from being implemented. "We're grandfathered with 5-Hour," team owner Barney Visser said Saturday. "They're going to have to stay with Furniture Row. There's no limit [of years]. We had an open-ended contract that way, so they could stay as long as they want." NASCAR, which has declined to release specifics of the grandfather clause, confirmed the accuracy of Visser's statement.
