NFL owners approved eliminating overtime in preseason games and expanded selection of jersey numbers for receivers, running backs and defensive backs. The league also will allow on-field officials to get certain “objective information” from the replay official and designated members of the officiating department “when clear and obvious video evidence is present.” During a virtual meeting Wednesday, the 32 owners also tabled a proposal by the Philadelphia Eagles that a team be given two chances per game to retain possession after a score by converting a fourth-and-15 play from its 25-yard line.
