SANTA CLARA, Calif. — The San Francisco 49ers will not pick up the contract option on pass rusher Elvis Dumervil.

The team announced the move to part ways with the 34-year-old Dumervil on Friday. The 49ers also said they tendered a one-year contract to exclusive rights free agent running back Raheem Mostert and picked up the 2018 contract option for linebacker Dekoda Watson.

Dumervil led the 49ers with 6 1/2 sacks last season and has 105 1/2 in an 11-year career that also included stints in Denver and Baltimore.

Mostert played 11 games last season and finished with six carries for 30 yards while adding a team-high eight special teams tackles.

Watson had four defensive tackles and six tackles on special teams in 14 games last season.
