Wilkerson was carted off the field during Wednesday's practice after absorbing a hit on a kickoff, Zack Cox of NESN.com reports.
Wilkerson, who was down on the field for several minutes before being carted to the locker room, was transported away for off-site medical evaluation. The wideout made a splash in the Patriots' preseason opener last Thursday with eight receptions for 99 yards on 12 targets, putting him in a good early position to be included on the season-opening roster. He's been competing for a depth role in a receiver corps headed by DeVante Parker, Kendrick Bourne, Jakobi Meyers and Nelson Agholor.
