Los Angeles Chargers' Melvin Gordon could miss tie against Tennessee Titans

The Los Angeles Chargers could be without standout running back Melvin Gordon when they face the Tennessee Titans on Sunday in London.

The club downgraded Gordon's status to questionable on Saturday due to a hamstring injury. They also promoted rookie running back Detrez Newsome from the practice squad and released linebacker Emmanuel Ellerbee.

ESPN's Adam Schefter reported Gordon "will most likely be a game-time decision" for the 9:30 a.m. ET kickoff.

Gordon was listed on Friday's injury report as a limited practice participant, but he wasn't given a status for Sunday's game.

"I think it was just sore," Chargers coach Anthony Lynn told reporters of Gordon's injury after Friday's practice. "We had a long plane ride. He probably didn't drink enough water.

"We were just being extra cautious with him and we just held him out."

Gordon is having a strong season for the Chargers. He is averaging 5.1 yards per carrying, has scored nine total touchdowns and leads the AFC with 745 yards from scrimmage (466 rushing, 279 receiving).

If Gordon can't play, Austin Ekeler would become the primary back. Ekeler has 263 rushing yards -- he is averaging 6.4 per carrying, second in the NFL among qualified leaders -- and has caught three touchdown passes.

Justin Jackson (three carries) and Newsome (one) would be the backups.
