Vikings head coach Kevin O'Connell said Wednesday that Jordan Addison is in concussion protocol and will not be available for the team's second joint practice with the Tennessee Titans on Thursday or Saturday's preseason game.
He suffered "light" symptoms in the aftermath of a catch that took him to the ground during a two-minute drill earlier in the week, according to O'Connell, who added his first-round rookie could return as early as Monday.
Addison was not seen Wednesday during the on-field portion of the first of two Vikings-Titans joint sessions.
This is the second time since joining the team that the 5-11, 175-pound Addison has missed practices due to health issues.
