Horton's back injury could end his season, and maybe his career. Optimism is fading that Horton, 29, will be able to play this season and there is growing concern that his career might be finished. Horton signed a seven-year, $37.1 million dollar contract last summer and has only suited up in 35 games with Columbus. Horton has been diagnosed with “degeneration” of the entire lumbar region of his spine. Surgery has not been scheduled or ruled out, but it is viewed as a last resort. It’s a delicate procedure, with no guarantee of relief.
