The AFL-CIO is warning that a lockout by NFL owners could cost thousands of Americans their jobs and American cities more than $140 million in lost revenue. It also urged owners to release financials statements, something NFL Players Association executive director DeMaurice Smith has sought for more than a year. The AFL-CIO called the owners' refusal to provide financial documents "troubling." Players at the season-opening game Thursday night night and six of Sunday's 12 afternoon game walked to the hash marks before their games and raised their index fingers as a sign of union solidarity. After, some players cited the very language that appeared in the letter sent to the owners. The current collective bargaining agreement expires in March. Every city could lost $140 million, if their no football next season for the NFL.
