The San Diego Chargers have released left tackle Jared Gaither, which will cost them a $6 million hit against the salary cap.
Gaither was signed to a four-year, $24.5 million contract after playing well in the final five games of 2011. But he developed a mysterious back injury early in training camp last summer and was slow to return, raising questions about his work ethic. He played in only four of the first 10 games before injuring his groin and going on injured reserve.
The Chargers are expected to take an offensive lineman in the draft next month.
