McCarthy (knee) is not practicing Monday, and it is unclear if he will travel to Cleveland for joint practices, Dane Mizutani of the St. Paul Pioneer Press reports.
McCarthy excelled during his preseason debut to the tune of two passing touchdowns and 188 yards through the air. The rookie also completed 11 of 17 passes and finished with a 116.8 passer rating. It is unclear how serious his knee soreness is, but it would not be surprising to see the Vikings exercise caution with the 10th overall pick in this year's draft. If McCarthy ultimately misses more practice time, Sam Darnold would presumably get all of the first-team reps while Nick Mullens and Jaren Hall continue competing for the No. 3 role under center.
