McCarthy has been limited in practice this week as he deals with a mild deltoid sprain in his ankle. Despite the injury, the Vikings want to maximize the 23-year-old’s preseason reps with Kyler Murray already locked in as the start. It’s also possible McCarthy competes with Carson Wentz for the No. 2 quarterback spot as both players split second-team reps earlier this week. O’Connell said the team is aiming to have McCarthy ready to start against the Broncos Friday, but also added, “if we can’t get him there, we can’t get him there.” Ultimately, the ankle injury seems minor but may prevent McCarthy from seeing valuable reps as he fights to stay as the QB2 on the Vikings depth chart.
