Jackson (undisclosed) was discharged from a local New England hospital and joined his Eagles teammates for their return trip to Philadelphia following Saturday's 24-21 loss, Tim McManus of ESPN.com reports.
Jackson suffered a serious injury on the opening kickoff after his head appeared to collide with Lan Larison's leg. Jackson left the field in an ambulance before being taken to a local hospital, where CT scans came back negative. It's the best-case scenario for the Arkansas product, but given what transpired Saturday, it seems unlikely that Jackson will play in Friday's preseason finale against Cincinnati.
