HOUSTON -- The Houston Texans signed wide receiver DeAndre Hopkins to a five-year, $81 million contract extension with $49 million guaranteed, a source told ESPN's Adam Schefter.

Hopkins' $49 million guaranteed is the largest for any wide receiver in the NFL.

Hopkins had a breakout season in 2015, with 111 catches for 1,521 yards and 11 touchdowns. Last year, Hopkins' production dipped -- he finished the year with 78 catches for 954 yards and four touchdowns -- with quarterback Brock Osweiler throwing him the ball. During the offseason, Texans head coach Bill O'Brien said even though Hopkins' stats were not were they were the year before, he helped the team in other ways on offense and in the locker room.

The Texans exercised Hopkins' fifth-year option in April 2016, so the wide receiver was entering the last season of his rookie contract. Last year, Hopkins left training camp for one day because he wanted a new deal. This year, he reported to camp, telling ESPN's Dan Graziano he did not hold out "because I know I have a great team."
