The Steelers signed veteran punter
Mesko, in his fourth NFL season, was originally selected by the New England Patriots in the fifth round of the 2010 NFL Draft out of Michigan. He spent three seasons with the Patriots, averaging 44.2 yards per punt.
To make room for Mesko, the Steelers released second-year punter Drew Butler. Butler was signed as an undrafted rookie free agent by Pittsburgh in 2012.
The Steelers also claimed cornerback
To make room for Blake on the active roster, the Steelers released cornerback Isaiah Green.
