Pittsburgh Steelers tight end Heath Miller restructured his contract, reducing his salary-cap figure from $7.96 million to $6.46 million by converting $3 millon of his $5.162 million base salary into a signing bonus, a league source confirmed.

His base salary is now $1.974 million.

In 2014, his salary-cap figure has gone up to $9.466 million from an original figure of $7.966 million.

That's the final year of a five-year, $35 million contract extension originally signed in 2009 that included $12.5 million in guaranteed money.

The Steelers needed salary-cap space to sign Jonathan Dwyer, Shayne Graham and Fernando Velasco while placing La'Rod Stephens-Howling, Larry Foote and Maurkice Pouncey on injured reserve.

The Steelers are currently $1.488 million under the NFL salary-cap limit of $123 million.
