A single-vehicle wreck early Tuesday sent a Lawrence man to the hospital.

Shortly after midnight, Ray Ramey, 44, was driving south on Barker Avenue when he lost control, flipping his truck into a tree on the west side of the 2100 block. Ramey, who police said suffered nonlife-threatening injuries to his head, was flown by helicopter to a Kansas City area hospital, where he was in serious condition late Tuesday afternoon.

Police are investigating the cause of the wreck.
