4 Sam Koch P

Koch signed a two-year extension with the Ravens on Thursday.

The 37-year-old spent the first 14 seasons of his career in Baltimore, and he's set to remain there for another two years. Koch has a 39.8-yard net average on 100 punts over the past two seasons.

The Ravens reached a five-year contract extension with punter Sam Koch on Thursday. The deal is worth $16.25 million, which includes a $4 million signing bonus, according to multiple reports.

Koch's net punting average (43.3 yards) led the NFL in 2014 and ranked fourth best in league history. He was a first alternate to the Pro Bowl last season.

The 32-year-old Koch holds the franchise records for consecutive games played (144), gross average (45.0), net average (39.0) and punts inside the 20-yard line (251).

Ravens punter Sam Koch is a likely salary cap casualty, reports ESPN.com. The team can gain $1.6 million in cap room by releasing Koch, who finished 22nd in net punting average (38.9 yards).
