NFL Media Insider Ian Rapoport reports that based on initial exams, the injury is not believed to be serious, per a source.
Edelman's status will be updated as more news leaks.
The receiver injured himself during a one-on-one drill, then took himself off the field, slamming his helmet on the ground. He then had his lower leg examined by Pats trainers on the field before walking off under his own power, NFL Media's Courtney Fallon reported.
Encouraging news. Edelman came back from the PUP list earlier than expected, but as the story said, the Pats likely won't take a lot more chances with Edelman before the season starts.
