Last Wednesday, Minnesota Vikings defensive tackle B.J. DuBose tore the anterior cruciate ligament (ACL) in his right knee. Almost a week later the team decided to place him on waived/injured, but he is more than likely going to clear waivers, where the Vikings are then expected to place him on injured reserve.
By doing this, the Vikings have freed up a roster spot and they took advantage of it right away by signing defensive tackle Bruce Gaston. This may only be his third year in the NFL, but he has spent time with five different ball clubs. He has been on the rosters of the Arizona Cardinals, New England Patriots, Miami Dolphins, Green Bay Packers and Chicago Bears.

He originally signed with the Cardinals as an undrafted free agent following the 2014 draft, but was waived before the start of the season. The Patriots then signed him to their practice squad, but he was waived just a couple days later. The Dolphins then signed him to their active roster, waived him, and signed him to their practice squad once he cleared waivers. The Cardinals then claimed him off the Dolphins’ practice squad and put him on their active roster, but waived him soon after and signed him to their practice squad. The Packers then picked him off the Cardinals’ practice squad and signed him to their active roster toward the end of the 2014 season.
Gaston stayed with the Packers through the end of the 2014 season and eventually made it through the 2015 training camp as a part of their 53-man roster to start the season. He played in two games and recorded one tackle with the Packers before being waived once again and signed to their practice squad.
It was then the Bears’ turn to pick Gaston off of a practice squad and sign him to their active roster. He played in seven regular-season games with the Bears in 2015, recording 11 tackles, one tackle for a loss and one sack.
He now looks to earn a spot on the Vikings’ active roster to start the 2016 season, but it will not be an easy task as they currently have a lot of depth at defensive tackle.
