The Pittsburgh Steelers have locked up at least one of their wide receivers.
The Steelers signed wide receiver Antonio Brown to five-year, $42.5 million extension, according to league sources. He will receive a $8.5M signing bonus.
Brown, a sixth round draft pick in 2010, is in his third NFL season out of Central Michigan. He caught 69 passes for 1,161 yards and two touchdowns last season and had a 16.1 yards per catch average. The Steelers are still without the services of Pro Bowl wide receiver Mike Wallace, who has yet to show up at training camp and is seeking a long-term deal from the team.
