The Los Angeles Chargers announced a trio of roster moves before taking the field for practice on Monday, officially signing TE Antonio Gates, waiving RB Justin Jackson and signing TE Thomas Duarte to the practice squad.

The Bolts previously announced Sunday that they agreed to terms with Gates on his 16th season in 2018. Number 85 is the Chargers' all-time leader in receptions (927), receiving yards (11,508) and touchdowns (114). He's also caught the most touchdowns by a tight end in NFL history.

Meanwhile, Jackson was the Chargers' seventh-round pick (251st overall) in this year's draft out of Northwestern. The 6-2, 199-pound running back missed most of training camp and the preseason due to injury, but returned for the final preseason game, carrying the ball seven times for 18 yards.
