Now Lee and his booming leg will be a part of the 49ers even longer.

"Sometimes it's underestimated probably," 49ers coach Jim Harbaugh said of his punter. "Andy is one of those guys that wins games for our football team.

Lee has been a major — if not often overlooked — asset since San Francisco drafted him in the sixth round in 2004.

The 29-year-old has played in 128 games for the 49ers and holds team records in punts (723), yards (33,069), gross average (45.7), net average (38.9) and punts downed inside the 20-yard line (209). Since 2007, Lee's gross punting average (47.9) and net average (40.7) rank second in the NFL.
