Antonio Brown seeking new contract

Antonio Brown is not attending the Pittsburgh Steelers' first day of offseason workouts, a source told ESPN, and the All-Pro wide receiver is seeking a new contract.

Brown has three years left on a five-year, $42.5 million extension he signed in 2012. The former sixth-round draft pick led the NFL in catches (129) and receiving yards (1,698) last season, and he is one of the most accomplished young players in the league.

Brown, who will turn 27 in July, made a base salary of $6 million in 2014. The three-time Pro Bowler is due a base salary of $6 million this year, $8.25 million in 2016 and $8.71 million in 2017.

Fox Sports first reported Brown's missing the first day of workouts.

Offseason workouts and most of the practices, which begin for the Steelers in late May, are voluntary. The three-day minicamp that the Steelers will hold June 16-18 is mandatory for all players. The minicamp is the only offseason activity for which Brown could be fined for missing.

The Steelers typically don't re-sign players to new contracts until they are going into the final year of their deal. They make an exception with starting quarterbacks; the Steelers usually sign those players with two years left on their contract.

Pittsburgh has not had a significant training camp holdout since wide receiver Hines Ward in 2005. Ward missed the first two weeks of camp over unhappiness with his deal, which had one year and $1.66 million left on it.

The Steelers refused to negotiate with Ward until he reported to camp, and the two sides eventually agreed on a four-year extension worth almost $26 million.

Guard Alan Faneca skipped most offseason activities in 2007, Mike Tomlin's first year as head coach, after the team did not sign the perennial Pro Bowler to a new, long-term contract.

Faneca, however, reported to training camp on time and played out his contract before signing a five-year, $40 million deal with the New York Jets.

Brown set a number of Steelers records in 2014, including most touchdown receptions (13) in a season. He also led the NFL in a handful of categories, including receptions for first downs (85) and third-down catches (36).

He has 5,259 receiving yards in five seasons and also returns punts. He is sixth on the Steelers' career receiving yards list, 203 yards behind Hall of Famer Lynn Swann for fifth.

Brown is fourth on the Steelers' career receptions list with 390.
