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.

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).
