Bengals lose FB Tahi; sign Bob Johnson's nephew

The Bengals have signed long-snapper Adam Johnson to the practice squad. The team lost fullback Naufahu Tahi from its practice squad; he was signed to the Vikings 53-man roster.

Johnson, at 6-feet 5, 235 pounds, played at the University of Buffalo and was on the Kansas City Chiefs' practice squad from the beginning of the season until his release Oct. 17. Johnson first entered the NFL as a college free agent with Carolina in 2004 and on the Panthers practice squad that season. He was out of the NFL during the 2005 season.

His uncle, Bob Johnson, was the first player drafted by the Bengals in 1968 from the University of Tennessee. He played 12 seasons with the Bengals (1968-79).
