NEW YORK (AP) – The NFL’s on-field officials say the league planned to lock them out rather than negotiate a new contract.

Members of the NFL Referees Association were locked out June 3 after talks broke down. The league has been contacting replacement officials.

Scott Green, the NFLRA president, and past president Ed Hochuli, both current referees, say the NFL is jeopardizing the safety of the players, as well as the integrity of the game, by considering using officials they feel are unqualified.

The officials say their wage offer was for a smaller increase than they received in the collective bargaining agreement that expired in May. They also cite as issues higher wages for officials in the NBA, NHL and Major League Baseball, and the loss of a pension system.

BOSTON (AP) – The Boston Celtics have signed free agent guard Jason Terry.

The deal was reported earlier this month during a signing moratorium, then held up while the Celtics tried to work out a sign-and-trade agreement with the Dallas Mavericks.

Instead, Boston will use its mid-level exemption to sign the 2009 NBA Sixth Man of the Year.

The 6-foot-2 guard averaged 15.1 points per game for the Mavericks last year. He was second in the league with 138 made 3-pointers last season and is fourth in NBA history on the career list with 1,788.

Terry is seen as a replacement for Ray Allen, who signed as a free agent with the Miami Heat.

DETROIT (AP) – Baseball stadium Comerica Park is the latest Detroit landmark to be the subject of a bomb threat.

Police say an anonymous caller issued the threat in a 911 call around 8 p.m. Tuesday as the Tigers were hosting the Los Angeles Angels in front of 34,000 fans.

No announcement was made, nor was there a call for an evacuation as police searched the ballpark for an explosive device.

Detroit police Sgt. Eren Stephens says no device was found.

The threat followed two similar incidents in less than a week that shut down a tunnel and a bridge connecting Detroit and Windsor, Ontario, for hours.
