The Packers signed punter Tim Masthay to a four-year, $5.5 million contract extension that could keep in Green Bay until the end of the 2016 season.
Masthay received a $1.2 million signing bonus. He's entering the final year of his rookie deal -- which remains unchanged at $540,000 in base salary -- and could have become a restricted free agent in March 2013.
The deal was signed on the first day of training camp but was not announced by the Packers.
Masthay, 25, was 15th in the NFL in gross average at 45.6 yards per attempt.
