When the dust settled on Wednesday, only three of PFT’s top 20 free agents were unsigned and untagged and that number dropped to two when cornerback Sean Smith agreed to a deal with the Raiders.

Tackle Andre Smith is one of the other two and it looks like his market will start to heat up. Charles Robinson of Yahoo Sports and Darren Wolfson of KSTP in Minneapolis both report that the Vikings are expected to have Smith in for a visit.

Smith has spent his entire career with the Bengals since they made him the sixth overall pick of the 2009 draft, so Vikings coach Mike Zimmer is familiar with Smith’s game from the time he spent running the defense in Cincinnati. The Vikings reworked right tackle Phil Loadholt’s contract, but they’ve made upgrading their offensive line a priority this offseason — they signed guard Alex Boone Wednesday — and may find Smith provides one over a player coming off an Achilles tear.

The Vikings aren’t the only team with Smith on their radar, however. Wolfson adds that the Buccaneers are also showing interest in Smith, who worked against current Bucs defensive line coach Jay Hayes’ charges in practice when Hayes held the same job with the Bengals.
