The New England Patriots and veteran safety Adrian Phillips reached agreement on a three-year contract extension that includes $7.25 million guaranteed, a source told ESPN's Adam Schefter on Saturday.

Phillips, 29, has become a key cog on the defense since signing a two-year, free-agent contract with the Patriots in 2020. He is third on the team with 70 tackles and his four interceptions rank second on the club.

In November, coach Bill Belichick said Phillips "almost always does the right thing" and compared him to longtime Patriots safety Patrick Chung.
