Melvin Gordon, a star running back for the Los Angeles Chargers, did not end his contract holdout until Thursday, but as a result of an injury to Justin Jackson, there is a chance Gordon will play on Sunday in his team’s road game against the bottom-feeding Miami Dolphins at 1 p.m., Eastern time.

“We understand that Melvin’s been back for a day and a half, so we have to be careful if he plays, how much he plays and even if he plays at all,” Chargers Coach Anthony Lynn said on Friday.

Gordon, who averaged an eye-popping 5.1 yards a carry in 12 games last season, has long been one of the most talented running backs in the N.F.L., but he engaged in a fruitless standoff with his team in hopes of securing a hefty raise. In contrast to Ezekiel Elliott of the Dallas Cowboys, whose holdout netted him a new contract with $50 million in guaranteed money, Gordon’s holdout cost him about $1 million and he is still playing on his original deal.

The Chargers have gotten terrific production from Austin Ekeler in place of Gordon, but with Jackson having been ruled out with a calf strain, Los Angeles is thin at running back, which resulted in Gordon’s being declared active on Saturday.

Gordon told reporters on Friday that he would be ready.

“It’s not like I’ve been sitting around and I’m coming in overweight or anything like that,” he said. “But it’s not like I get a preseason game to get warmed up. You kind of get in and get right in the fire.”
