Update, 9/27/2012, 6 a.m. EDT: The National Football League announced late Wednesday night that it had indeed reached agreement on a new collective bargaining pact with its referees, who were expected to be back at work as of Thursday’s game between Cleveland and Baltimore. 

As the simmering controversy over the botched call that marred Monday’s Packers-Seahawks game appeared to be moving National Football League management and the referees’ union toward a new collective bargaining agreement, the head of the NFL players union said Wednesday that his members would consider pursuing legal action against the league over what he called the “health and safety issues” the replacement refs are creating on the field.
