(KLZA)-- Two Illinois men were injured early Monday morning in a single-vehicle wreck on I-29 in Holt County, Missouri about six miles south of Mound City. 

The Missouri Highway Patrol says 30-year-old Allen Wheeler was southbound on I-29 when his car went off the east side of the roadway into the median.  The vehicle struck several large rocks, started to overturn and became airborne, landing on the passenger side in a creek.

Wheeler and a 28-year-old passenger, Joshua Quintern, were both transported to Mosiac Life Care in St. Joseph.  The Patrol says Wheeler suffered moderate injuries and Quintern suffered minor injuries.

Both men were wearing safety devices at the time of the wreck.

The wreck was shortly before 3:50 Monday morning.
