The Chargers placed a second-round tender on restricted free-agent cornerback Michael Davis and exclusive-rights tenders on defensive end Isaac Rochell and offensive tackle Trent Scott.
Davis, 25, started all 12 games in which he appeared last season, finishing with 39 tackles and two interceptions. Initially signed as an undrafted free agent out of Brigham Young, Davis is entering his fourth season.
Rochell was a seventh-round pick in the 2017 draft. He has appeared in 35 career games with three starts.
Scott was undrafted out of Grambling State. In his two NFL seasons, he has played in 25 games with 10 starts, nine of which came last season when the Chargers were thinned by injury up front.
