Coach Mike Zimmer said Monday the team was "looking at everything now" in regards to adding depth to its backfield after losing the explosive rookie for the season, as Cook was placed on injured reserve Thursday.
Cook sustained a season-ending ACL tear in Sunday's 14-7 loss to the Detroit Lions.
Minnesota likely won't feature a running back the way it did with Cook, who had 74 carries for 354 yards and two touchdowns before he went down in Week 4. Cook started his National Football League career off with a bang, rushing for 127 yards on 22 attempts during the Vikings' Week 1 win over the New Orleans Saints.
Ridley was signed by the Denver Broncos back in late July, but he was released right before the season start.
Ridley's best season came in 2012 when he had 290 carries for 1,263 yards and 12 touchdowns for the Patriots. He played in one game with the Atlanta Falcons a year ago, carrying the ball three times for seven yards.
Peterson was not brought back as a free agent after last season, and was replaced in the starting lineup by Cook, a second-round pick out of Florida State.
After staying with the Patriots from 2011 through the 2014 season, he played with the New York Jets in 2015 and the Atlanta Falcons in 2016. If McKinnon can not go Monday night against the Bears for any reason, Ridley would end up the primary backup to starter Latavius Murray.
