The Kansas Highway Patrol is on the scene of a semi rollover in Sumner County. KHP says the driver swerved to miss a deer while southbound on Highway 81 near 150th Street South. 

The grain hauler truck rolled into a ditch and landed on its side.  The driver wasn't hurt and the deer ran away unharmed.

We're told there's a big mess in the area and KHP had to shut down both lanes of traffic for the time being.
