The Giants released Kelley on Sunday, Art Stapleton of The Bergen Record reports.
Kelley was a free agent for most of the offseason after playing in all 17 regular-season games for the Chargers in 2023, finishing with 405 rushing yards and two touchdowns on 107 carries. He caught on with the Giants on Aug. 15, and in his last preseason outing Saturday against the Jets, he rushed for 40 yards on eight carries. Kelley will look to sign with another team in need of backfield depth.
