Broncos linebacker Corey Nelson suffered a tear around his elbow during practice Wednesday and will be placed on season-ending injured reserve, according to two NFL sources. Nelson will have surgery next week, Broncos coach Vance Joseph said. “Corey’s had a great year, both on defense and special teams,” Joseph said. “That’s a big loss for us, but it happens.” Nelson’s injury, which leaves the Broncos without one of their top special teams players, was one on a long list for Denver heading into its game at the Los Angeles Chargers on Sunday afternoon. The Broncos will also be without right tackles Menelik Watson (calf) and Donald Stephenson (calf) and wide receivers Cody Latimer (knee), Isaiah McKenzie (ankle) and Emmanuel Sanders (ankle). To fill Nelson’s spot on the roster, the Broncos will sign inside linebacker Jerrol Garcia-Williams from the team’s practice squad, Joseph said Friday.
