NeXovation Inc. and Dover Motorsports Inc. have pushed back the closing on the company's purchase of the Nashville Superspeedway again with an updated agreement to conclude the sale within the next 60 days.

In a release Monday, NeXovation officials said the company has lined up the funding for the purchase but need more time for closing.

NeXovation made a payment of $400,000 on Friday with Dover agreeing to extend the closing, bringing the company's investment on its purchase to $2.5 million.

Dover Motorsports agreed last May to sell the superspeedway in a deal worth nearly $46 million.

The 1.33-mile, concrete track opened in 2001 hosting NASCAR trucks and Nationwide races along with an Indy Racing League event through 2008. Dover closed the track, except for testing, in 2011.
