Stefon Diggs was back on the field practicing, and Bills coach Sean McDermott said whatever lingering issues from last season that raised concern and confusion over the absence of Buffalo’s top receiver a day earlier have been resolved. McDermott expanded and clarified on the limited statements he made a day earlier by saying Diggs didn’t skip the team’s mandatory session on Tuesday, but was in fact excused. He also said a series of discussions airing out Diggs’ concerns have left the team and receiver “in a real good spot.” Diggs’ participation was his first with the team this offseason after he skipped the Bills voluntary workout and practice sessions.
