Tanner was transported to Medical College of Georgia Hospital after being rear-ended shortly before 9 p.m. by a truck driven by Willie Ferrell on the 1700 block of Tobacco Road. He is still listed in critical condition, according to a hospital spokeswoman.
Charges of following too closely are pending against Ferrell, Griffin said. Authorities believe speed played a factor in the crash.
A witness told deputies it appeared as though Ferrell was attempteing to swerve out of the way before he struck the cyclist with his 1978 Chevrolet C-10.
Griffin said deputy reports show Tanner was properly equipped with all reflectors. The report did not state if Tanner was wearing a helmet.
