The Chicago Bears have agreed a two-year contract extension with Tony Fiammetta.
The fullback joined the NFC North side on a one-year deal after leaving the New England Patriots in 2012.
The team believes that the 27-year-old's arrival has helped running back Matt Forte rush for 1,229 yards.
Fiammetta, who has also had previous spells with the Dallas Cowboys and Carolina Panthers, will remain with the side until the end of the 2015 season.
