Right tackle Phil Loadholt is out for the rest of the season, according to an NFL.com report.

Loadholt tore a 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.

Loadholt is the second Vikings offensive lineman to be lost to a torn pectoral muscle this season. Right guard Brandon Fusco suffered a similar season-ending injury back in Week 3.

Loadholt, 2009 second-round pick, is in his sixth season with the Vikings. Loadholt has struggled in pass protection this season, allowing five sacks and 33 total pressures, according to Pro Football Focus. But he was solid as a run blocker again.

We will get a chance to ask head coach Mike Zimmer for more on Loadholt's injury at 2 p.m.
