SAN DIEGO – With two games left in the season and fighting for their playoff lives, San Diego Chargers quarterback Philip Rivers has not been an active participant in the early portion of practice available to reporters this week.

Rivers was in uniform, but did not do any individual drill work on Tuesday. On Wednesday, Rivers was not on the field during the early portion of practice available to reporters.

No reason was given for Rivers’ absence from practice by the team on Wednesday. However, Rivers was listed as having a chest and back injury on the team’s injury report last week. Rivers has started 142 straight games, the NFL’s second-longest active streak behind Eli Manning (166).

Along with Rivers, running back Ryan Mathews (ankle), receiver Keenan Allen (shoulder), defensive tackle Corey Liuget (ankle), tight end Ladarius Green (concussion, ankle) and punter Mike Scifres (shoulder) were not on the field for the early portion of practice on Wednesday.
