Back from the bye, the Los Angeles Chargers announced a flurry of transactions on Tuesday as they gear up for the second half of the season.

The Bolts signed tight end Jeff Cumberland, activated linebacker Denzel Perryman from Reserve/Injured-Designated for Return and waived linebacker Josh Keyes and tackle Tyler Marz. In addition, the team signed center-guard Cole Toner to the practice squad.

Cumberland is a 6-4, 260-pound tight end who is on his third stint with the Chargers. However, this marks the eight-year veteran's first stint on the 53-man roster. Cumberland first signed with the team in 2016, but spent the entire campaign on IR after suffering an Achilles injury in the preseason. He rejoined the team this past offseason, but missed most of training camp with a minor injury. Cumberland did appear in two preseason games before being released during final roster reductions. The former Jet caught 86 passes for 1,119 yards and 10 touchdowns over 65 career games in New York, many of which came with Head Coach Anthony Lynn on the team's staff.

Meanwhile, Perryman returns to the active roster after an ankle injury cost him the first half of 2017. The third-year linebacker suffered the injury in the first preseason game, and was subsequently placed on IR a week before the season opener. Perryman was designated for return in mid-October, and returned to practice before the Week 7 match against the Denver Broncos. Per NFL rules, while those designated to return can practice after six weeks, they must miss at least eight games before being back on the active roster. The 5-11, 240-pound Perryman has totaled 126 tackles, nine tackles for loss and four sacks over 26 career games.

In order to make room for Cumberland and Perryman, the Chargers waived Marz and Keyes. Marz was signed off the Tennessee Titans' practice squad in late September, but was inactive all six games he was on the active roster. Keyes was signed in mid-October, appearing in two games on special teams.
