All indications have been that Mack was likely to test the open market this year, as his contract is designed to give him an out before the start of free agency.
Either way, Mack is in line for another sizable contract that could leave him among the highest paid interior offensive linemen in the league.
Mack, 29, is technically in the second year of his five-year, $42 million contract that included $26 million guaranteed. He would make annual base salaries of $8 million over the remainder of the agreement and the deal includes a no-trade clause.
In 2015, Mack appeared in all 16 games and was rated by Pro Football Focus as the No. 16 center out of 40 qualifying players.
