The Vikings added another offensive lineman to the rebuilding project.

Freddie Tagaloa, a hulking 6-foot-8-inch, 314-pound guard, signed a three-year contract after trying out during the Vikings rookie minicamp May 5-7, a league source told the Star Tribune. He's currently the only player to sign a deal after a couple dozen undrafted rookies and veterans were brought in for a tryout earlier this month.

The Vikings made the signing official on Tuesday. Defensive lineman B.J. Dubose, a 2015 sixth-round pick, was waived to make room on the 90-man roster.

An infusion of new faces has greeted offensive line coach Tony Sparano this offseason during rebuilding efforts of last year's tattered group. Tagaloa is the eighth new offensive lineman, a group which currently takes up 15 of the 90 offseason roster spots.

Tagaloa will start off at guard, where he finished his college career after beginning as a left tackle. He struggled to stay on the field in college, transferring to Arizona from Cal. NCAA rules forced Tagaloa to sit out the 2014 season and he returned to an injury-plagued campaign in 2015. He reportedly tore his posterior lateral ligament and medial collateral ligament in the same season.

The Houston Chronicle first reported Tagaloa's agreement.
