Mack recently visited with the Jacksonville Jaguars,
China Jerseys, who have not yet offered him a contract. The Browns would have five days to match any offer to Mack, who was tagged as Cleveland's transition player before free agency began. Mack can play next season in Cleveland for $10 million.
Pettine calls Mack's situation "fluid" and says there's some optimism the Browns may hold onto the Pro Bowler because "nothing has happened so far."
