The Vikings waived Mitchell on Monday, Chris Tomasson of the St. Paul Pioneer Press reports.
Mitchell missed a portion of training camp due to a quad injury, but when available, he made a strong impression and was vying for a roster spot. However, the undrafted product out of UAB now finds himself among the first waves of cuts ahead of Tuesday's 53-man roster deadline. Per Tomasson, it's possible Mitchell returns to the team's practice squad if he clears waivers.
