Owner says Chargers will strive to stay in San Diego

The San Diego Chargers announced Friday they will not move to Los Angeles for the 2016 season and will double their efforts to reach a deal to remain in their hometown.

Chargers Chairman Dean Spanos, disclosing his decision in an open letter to Chargers fans, said the team still had an agreement with the Los Angeles Rams to share their stadium in Inglewood, "but my focus is on San Diego."

"This has been our home for 55 years, and I want to keep the team here and provide the world-class stadium experience you deserve," Spanos said after an afternoon meeting with San Diego officials.

The announcement means Los Angeles will have one NFL team when the season opens this fall. The Rams are expected to play the first three seasons in the Coliseum while a state-of-the-art stadium is being built in Inglewood. Should the Chargers remain in San Diego, the Oakland Raiders have the right to share the Inglewood stadium.

"We are very supportive of the decision by Dean Spanos to continue his efforts in San Diego and work with local leaders to develop a permanent stadium solution," Commissioner Roger Goodell said in a statement. "NFL ownership has committed $300 million to assist in the cost of building a new stadium in San Diego. I have pledged the league's full support in helping Dean to fulfill his goal."

• The NFL says reported concussions rose 58 percent in regular-season games to the highest number in any of the past four years. Jeff Miller, the NFL's senior vice president of health and safety policy, said the league will study what might have caused the incidence of head injuries to rise so much this season. He speculated that screening more players had led to more concussion diagnoses.

• Kansas City's Travis Kelce signed a five-year extension worth $46 million that makes him one of the NFL's highest-paid tight ends. Over the past three seasons he's caught 139 passes for 1,737 yards and 10 touchdowns.

Jason Day, the defending champion and No. 2 player in the world, also missed the cut, as did Rickie Fowler, the No. 4 player in the world, and Justin Rose, No. 7 in the world.

Gary Woodland and K.J. Choi shot 5-under 67s Friday and shared the lead at 9-under 135.

The Los Angeles Dodgers and free-agent second baseman Howie Kendrick have agreed on a $20 million, two-year contract, a person familiar with the deal said.

Kendrick, 32, batted .295 with nine home runs and 54 RBI last season. His return seemingly solidifies second base, where options were seen as slim.
