We don’t yet know when Kolar could return, but he will have to miss at least the next four games now that he’s on injured reserve. Kolar was seeing a decent workload during the first two weeks of the season, as his 72 snaps led all Chargers tight ends, while his 24 routes run were only one fewer than David Njoku’s 25. With Njoku (fibula) also on injured reserve, Oronde Gadsden could be in line for a significant workload over the next several weeks.
