The San Francisco 49ers and Fred Warner agreed to a three-year, $63 million contract extension, which will make Warner the highest-paid linebacker in NFL history, his agency announced.

The 49ers are still co-favorites to win the NFC West, and betting against Kyle Shanahan has been a losing effort for the majority of his NFL career.

The 49ers are signing linebacker Fred Warner to a three-year contract extension worth $63 million with $56 million guaranteed, according to a Monday afternoon report from Adam Schefter of ESPN. The deal makes him the highest-paid linebacker in the NFL.
