As is getting destroyed at home by the 1-3 Carolina Panthers didn’t hurt enough, the real salt in the wound was three substantial injuries to defensive players.

Desmond Bishop suffered a knee injury in the second quarter of Sunday’s game against the Panthers. Despite being to limp off the field, the Vikings announced today that Bishop’s season has come to an end with a torn ACL in the right knee. The game against Carolina was Bishop’s first and last start of the season. Bishop, who struggled to get on the field at linebacker despite it being one of the Vikings [many] weaknesses likely means it was his last game in Minnesota. Desmond Bishop, 29, was only signed to a one-year deal and will be a free agent after 2013.

Harrison Smith, one of the few Vikings defensive players who has been very impressive this season, is now dealing with a turf toe injury. Smith is scheduled to have an MRI to determine the severity of the injury.

Finally, rookie Xavier Rhodes also suffered an injury that removed him from Sunday’s contest. Rhodes sprained his ankle while defending an incomplete pass deep to Ted Ginn Jr. in the second quarter. Although he returned to the game for a short period, he did not play in the second half. Rhodes is also scheduled for an MRI to determine how much time, if any, he will miss. When asked about the injury, Rhodes said “Nothing that can hold me back.”

The Vikings defense, now riddled with more injuries, has already allowed 418 yards per game (the second worst in the NFL) and 31.6 points per game (the third worst in the NFL).
