Percy Harvin vows to "explode" in 2015 season

Buffalo Bills wide receiver Percy Harvin has promised that he will "explode" back into life in the NFL in the 2015 season.

The 26-year-old has struggled with injuries for the past three seasons as he has bounced around three clubs, including the Seattle Seahawks, before landing with the Bills on a one-year deal.

Harvin is confident that he will produce the best season of his career with Rex Ryan's men in the 2015 campaign.

He told reporters: "The world has yet to see me really explode like I'm about to."

Harvin has recorded 332 receptions for 3,802 yards and 21 touchdowns in his six-year NFL career.
