The agents for both players announced the signings on Twitter on Tuesday.
The signings come on the same day when rookies reported to the team’s stadium for coronavirus testing in preparation for training camp.
The 6-foot-5, 265-pound Gross-Matos was the 38th overall player taken in April's draft after the defensive end made 17 1/2 sacks the last two seasons for Penn State. He's expected to replace Mario Addison, who left via free agency, as the team's starting end.
Pride, a cornerback, finished his college career at Notre Dame with 121 tackles, 18 pass breakups and four interceptions in 45 games and could compete for a starting spot. He was also a sprinter for the Fighting Irish track team.
The Panthers previously signed first-round draft pick Derrick Brown, a defensive tackle from Auburn. That leaves Carolina with four unsigned draft picks, including its other second-round pick, safety Jeremy Chinn.
