The Jacksonville Jaguars have made Brandon Linder one of the NFL's highest-paid centres.
Linder signed a five-year contract extension worth a little more than $50m on Tuesday.
Linder's $10 million average salary is the most of any centre in the league, and the deal includes more than $20 million guaranteed.
NFL Network reported the guaranteed money at $24m.
Atlanta's Alex Mack and Dallas' Travis Frederick are the only NFL centres with more guaranteed money.
Linder, a third-round draft pick from Miami in 2014, has started 31 games in three seasons.
He missed two games because of knee and ankle injuries last year. He also sat out one game as a rookie and missed 13 in 2015 because of a shoulder injury.
