Steelers wide receiver Antonio Brown restructured his contract and freed up $4 million worth of cap space for Pittsburgh, a league source told ESPN NFL Insider Adam Schefter.
The moves comes after Pro Bowl safety Troy Polamalu and tight end Heath Miller signed three-year contracts Wednesday.
The Polamalu deal is for $20 million total and saved Pittsburgh $4.5 million against the cap this year, a league source told Schefter.
Miller signed a two-year extension through the 2016 season that will reduce his cap hit for 2014 by more than $3 million, according to multiple reports.
The Steelers had been roughly $15.25 million over the cap after outside linebacker Jason Worilds signed a one-year, $9.75 million contract Tuesday.
