The NFL has given the Cleveland Browns a 24-hour extension to sell the remaining tickets for Sunday's game against San Diego and avoid a TV blackout.

As of Thursday afternoon, the Browns said there were "a few thousand tickets" left. For a game to be aired on local TV, the league requires a game to be sold out 72 hours before kickoff.

The Browns have until 4 p.m. Friday to sell the tickets. The team has not had a game blacked out since its expansion return in 1999.

After Sunday's game, the Browns have three more home dates. A Dec. 10 game against Pittsburgh is already a sellout, but there are tickets available for games against Oakland and Jacksonville.
