Byrd (arm) became a free agent Wednesday after the Panthers declined to tender him a contract for 2019, freelance NFL writer Howard Balzer reports.
Byrd landed on injured reserve in late November after suffering a broken arm Week 12 against the Seahawks. The 26-year-old had only one catch for eight yards in eight games with Carolina in 2018, numbers that may explain why the team opted not to retain him for another year.
