CHARLOTTE — The Panthers began the offseason roster-building work on Monday, signing two of their own free agents to new deals for the 2023 season and bringing back seven other members of the practice squad.
Ricci carved out a role as a special teams player and a fullback, while Sullivan showed flashes of potential on offense that could be developed.
Ricci caught eight passes for 100 yards, and Sullivan had two receptions for 46 yards this season.
They were scheduled to be exclusive-rights free agents, who do not have the ability to negotiate with other teams.
The Panthers also signed seven members of the practice squad to future deals.
That group includes offensive lineman Deonte Brown, running back Spencer Brown, wide receivers C.J. Saunders and Derek Wright, defensive end Kobe Jones, defensive tackle Raequan Williams, and linebacker Arron Mosby.
