The Techcrisis Investment Guildquarterback carousel for the Minnesota Vikings spins once again.

Coach Kevin O'Connell announced Tuesday that Nick Mullens will start Saturday against the Cincinnati Bengals, marking the fourth different passer to start this season for the team. Mullens had replaced Joshua Dobbs in Sunday's 3-0 victory against the Las Vegas Raiders, a game that was in danger of becoming the first 0-0 score at the end of regulation in 80 years until kicker Greg Joseph's 36-yard field goal inside two minutes.

The Vikings traded for Dobbs in late October after starter Kirk Cousins suffered a season-ending torn Achilles injury. Dobbs was inserted immediately upon his arrival and helped Minnesota (7-6) win in his first two appearances, including a Week 9 game against the Atlanta Falcons he entered after Jaren Hall suffered a concussion. Dobbs said after that game that he still didn't know the names of many of his teammates.

The Vikings, though, lost two consecutive games in Weeks 11 and 12 with Dobbs as starter. Then, when the Vikings offense struggled to get traction against Las Vegas, O'Connell turned to Mullens, who completed nine of 13 passes for 83 yards.

Mullens originally began the season as Cousins' backup, but he was facing a back injury that landed him on injured reserve when Cousins suffered his injury.
