Thornton underwent surgery this past Monday to repair a fractured clavicle, Jeremy Fowler of ESPN.com reports.
The report notes that Thornton's recovery period should be in the 6-to-8 week range, which sets the stage for the 2022 second-rounder to miss time out of the gate this season. Once he returns to action, the speedy rookie will look to carve out a role in a New England wideout corps that also currently includes DeVante Parker, Jakobi Meyers, Kendrick Bourne and Nelson Agholor.
