But Rosenior believes James can be available for Tuesday night’s meeting with Leeds at Stamford Bridge.
“Reece, he's so close and he should be fit for Tuesday,” Rosenior said post-match on Saturday.
“I know I said that today, but honestly, at the moment with the games that we've got, everything is day by day.
“He's really, really close. There's not a major problem at all and it'll be great to have him available for these on Tuesday.”
Rosenior added: “To be honest, Reece was out running yesterday. That just wasn't right and it's not right again. We're still in the midst of a really, really difficult period of games.
“It's just a knock. It's pain management issue. The amount of games that we've got hopefully comes back fully fit, fully rested for Tuesday.”
