JGR announces driver change for XFINITY Iowa race

Matt Tifft will not be behind the wheel of a NASCAR
vehicle this weekend at Iowa due to an injury.

Joe Gibbs Racing announced Tuesday a driver change for the XFINITY Series' American Ethanol E15 Presented by Enogen at Iowa Speedway (June 19, 1:30 p.m. ET, FS1, MRN, SiriusXM NASCAR Radio). 

Under recommendations from his doctor, Matt Tifft will sit out for the main event as he undergoes treatment for a disc condition in his back.

Instead, Sam Hornish Jr. will sit in the driver's seat of the No. 18 Toyota for the 250-lap event. 

Tifft, a Joe Gibbs Racing development driver, has had six starts in the NASCAR XFINITY Series this season, including top-10 finishes in his last two races, at Talladega and Dover.

Hornish Jr., a full-time Sprint Cup Series driver in 2015, also competed in three XFINITY Series events last season for Biagi-DenBeste Racing.

Tifft also had been scheduled to run the NASCAR Camping World Series' Speediatrics 200 in the No. 11 Red Horse Racing Toyota. He tweeted on Tuesday that he would not be competing at all this weekend at Iowa.
