He played in all 16 games with the Bears last season and totaled six tackles, two sacks and two passes breakups.
Lynch, a fifth-round pick by the 49ers in 2014, has 105 career tackles with 20 sacks, 35 tackles for loss and 10 pass breakups.

To make room on the roster, the Jaguars released running back Jeremy McNichols and defensive end Chuck Harris.
The Jaguars plan to be more flexible schematically by interchanging the 4-3 and 3-4 alignments on base downs.
Last season, the Jaguars allowed 139.3 yards per game, which ranked as the fifth-highest in the league.
The Jaguars used seven of their 12 picks in last month’s draft to select defensive players. They chose former Florida cornerback CJ Henderson with the ninth overall pick in the first round and former LSU edge rusher K’Lavon Chaisson with the 20th overall pick.
In free agency, the Jaguars signed former Arizona Cardinals defensive tackle Rodney Gunter to a three-year, $18 million deal, $11.15 million guaranteed.
They also extended one-year deals to defensive linemen Al Woods ($2.75 million) and Cassius Marsh ($600,000).
They re-signed defensive end/special teams player Lerentee McCray to a one-year, $1 million contract and extended a one-year, $2.25 million contract to veteran cornerback Rashaan Melvin.
The Jaguars applied the non-exclusive franchise tag on defensive end Yannick Ngakoue, but he continues to express a desire to play for another franchise.
