Bengals sign Vakapuna to 4-year deal

FB Fui Vakapuna (7/215; 6-1, 253, Brigham Young) has signed a four-year deal that's worth $1.811 million, a source told ProFootballTalk.com. He started eight games at fullback last season with 291 yards on 54 carries and three touchdowns. The Bengals did not have a true fullback last year (Daniel Coats was more of a tight end). They consider him to be in the same mold as Fahu Tahi, who was on the Bengals practice squad in 2006, before being signed by Minnesota.
