Detroit Lions running back David Montgomery is set to return after missing two games with a rib injury. Montgomery, after a bye week, is available for Sunday's game at the Los Angeles Chargers after being a full participant during practice all week. Rookie Jahmyr Gibbs handled the majority of the workload in Montgomery's absence, rushing for a career-best 152 yards in a win vs. the Las Vegas Raiders on Oct. 30. Montgomery, who was injured during the Lions' victory over the Tampa Bay Buccaneers on Oct. 15, is the team's second-leading rusher with 385 yards on a team-high 94 carries with 6 touchdowns. Offensive coordinator Ben Johnson is looking for both Montgomery and Gibbs to get touches as the workload is divided between the two. Lions Pro Bowl center Frank Ragnow (toe) is set to return after missing the last game. Offensive lineman Jonah Jackson (ankle) also is expected to play after being inactive for three games.
