Update: The Bucs also signed fullback Josh Baker, per Scott Smith. Baker hasn't played a game since 2011, his only season in the NFL, which he spent with the New York Jets. He and Lane will presumably compete for a roster spot.
The Tampa Bay Buccaneers have signed fullback Jorvorskie Lane, according to his agent, David Canter. Lane was an undrafted free agent out of Texas A&M in 2009, and played one year in the NFL when he was with the Miami Dolphins during the 2012 season.
Lane replaces Erik Lorig, who signed a four-year, $4.8 million deal with the New Orleans Saints last months after spending four years with the Bucs. The team had reportedly wanted to re-sign Lorig, but his asking price was apparently too high.
In his one NFL season, Lane put up 13 rushing yards on 13 attempts, including two touchdowns, and added 11 catches for 79 yards and one touchdown. He was waived during final cutdowns ahead of the 2013 season and did not play in the NFL last year. Lane has also played for the Orlando Predators of the AFL, and the West Texas Roughnecks of the IFL.
It's not clear how important the fullback position will be in the Bucs' new offense, although Lovie Smith did note last week that the fullback position is "being pushed aside a little bit" (via Pewter Report). It's not inconceivable that the Bucs play the season without a fullback, instead preferring to add an extra tight end.
