Eden Prairie, MN (SportsNetwork.com) - Minnesota Vikings coach Mike Zimmer confirmed Monday that right tackle Phil Loadholt will miss the rest of the season.

Loadholt tore his pectoral muscle in the fourth quarter of Sunday's 24-21 loss to the Packers. He was replaced by backup offensive tackle Mike Harris and did not return to the game.

The 28-year-old Loadholt is the second Vikings offensive lineman lost for the season. Right guard Brandon Fusco suffered a similar injury early in the year.

Loadholt is in his sixth season with the Vikings. He started 11 games this season.

Harris started 12 games for the Chargers in 2012 and 2013.

Zimmer also told reporters that running back Matt Asiata is still going through the league's concussion protocol. Asiata was unable to play on Sunday against Green Bay.
