On Sunday, the Vikings got past the Saints without Mackensie Alexander. They might not have him for the rest of the postseason, either. 
Alexander is meeting with doctors to determine whether he needs surgery on his injured knee, Tom Pelissero of NFL.com (on Twitter) hears. Alexander is dealing with a small tear to his lateral meniscus, so it could go either way. A final decision is expected to come by the end of business on Tuesday, which will give the Vikings some time to formulate a game plan in advance of Saturday’s showdown with the 49ers.
The Vikings are already without Mike Hughes, who was placed on season-ending injured reserve on Friday. Without Alexander or Hughes, the Vikings deployed Trae Waynes, Xavier Rhodes, and Holton Hill at cornerback in their overtime victory.
Alexander, the No. 54 overall pick in the 2016 draft, is scheduled to reach free agency in March. Whether or not he returns to the Vikings, he’ll see a major pay bump from his four-year, $4.316MM rookie deal.
