Joe Gibbs Racing announced Tuesday that X-FINITY Series driver Matt Tifft will undergo surgery for removal of a low-grade glioma in the brain. The slow-growing tumor was found recently during treatment and evaluation for a disc condition in his back. Tifft will undergo surgery and rehabilitation soon. Once cleared by physicians, he is expected to return to racing. David Ragan will drive the Number-18 Toyota in Friday night’s Subway Firecracker 250 Powered by Coca-Cola at Daytona International Speedway. Tifft – who turned 20 on Sunday – has made six X-FINITY Series starts this season with a best finish of eighth twice, in back-to-back races at Talladega Superspeedway and Dover International Speedway. He’s also made three starts in the Camping World Truck Series.
