Mike McCoy was once passed over for a promotion in favor of Jeff Davidson.

Now, McCoy’s the one who gets to give Davidson a job.

The Chargers announced that Davidson had been hired as their offensive line coach, replacing the fired Joe D’Alessandris.

McCoy and Davidson were coworkers in Carolina for two years (2007-08). Then-Panthers coach John Fox bypassed the chance to promote McCoy to offensive coordinator to replace Dan Henning, going outside the organization to hire Davidson, who had been with the Browns.

McCoy was given the title passing game coordinator, which he held for two years before bolting for a coordinator job in Denver.

Davidson played five years in the NFL before moving into coaching. He was just let go by the Vikings, so he should have plenty of experience working with injury plagued lines.
