Denny Hamlin suffered a compression fracture in his lower back during Sunday's last-lap crash at Fontana, Calif.
Joe Gibbs Racing disclosed the injury Monday and said Hamlin was expected to be released soon from a Southern California hospital to return home. He has what is called an L1 compression fracture; essentially, the first vertebra in the lumbar section of his spine collapsed.
There was no immediate word on how long his recovery would take.
Hamlin was hurt during a crash with Joey Logano at the end of Sunday's race. He complained of lower back pain afterward.
