J.J. McCarthy showed plenty of arm talent in his preseason debut on Saturday.
Unfortunately for the Minnesota Vikings' first-round quarter, his knee will keep him out of practice on Monday night.
Vikings head coach Kevin O'Connell said McCarthy would be held out due to right knee soreness.
O'Connell added that McCarthy would be undergoing some tests, but Minnesota has no reason to think it's more than routine soreness.
McCarthy, the No. 10 overall pick of the 2024 NFL Draft, made his preseason debut Saturday in a 24-23 win against the Las Vegas Raiders in which he completed 11 of 17 passes for 188 yards, two touchdowns, an interception and a 116.8 rating.
On Saturday, Sam Darnold got the start, but McCarthy, 21, was due to get some run with the first-teamers on Monday and in joint practices against the Cleveland Browns this week. How McCarthy's tests come back will determine whether he practices at Cleveland.
The Vikings face the host Browns in Week 2 of preseason action on Saturday. Whether McCarthy will return to action is now to be determined.
