Jay Kimbrough critically injured in motorcycle crash on May 16 near Navasota.

A longtime adviser to Texas Gov. Rick Perry was in critical condition Saturday at a hospital in Central Texas after a motorcycle crash.

The Austin American-Statesman reports Jay& Kimbrough crashed his motorcycle around 6 p.m. Friday.

The newspaper reported that Trooper Jessie Jordan, a Department of Public Safety investigator, said witnesses told police that Kimbrough was driving his Harley-Davidson on the grassy median between Highway 6 south of Navasota, Texas.

Jordan said the witnesses reported that it did not appear that Kimbrough had been forced into the median by a vehicle and that it was unclear why he was riding there. Jordan said Kimbrough crashed when he ran into a turnaround between the lanes.

Kimbrough was taken to St. Joseph Hospital in Bryan, where he remained in critical condition Saturday evening, officials said.
