Rooney had been sent for some warm weather training in a desperate attempt to get him fit for the trip to London, but the game on Sunday has come too soon for the forward.
“Wayne’s come back, he’s fresh but he’s not ready for Chelsea,” Moyes said at his Friday press conference.
“He’s training, he’s on the grass, doing some running and looking quite good. He’s had a break, done a lot of strengthening work around his groin and hopefully enjoyed a few days in the sunshine as well. Hopefully he’ll benefit from it, but not for this game.”
Rooney aggravated an existing groin injury in the defeat against Tottenham on New Year’s Day and Moyes was reticent to give a specific date on his return.
“I don’t want to put a date on it just now as I don’t want to say he’ll be fit for whatever game and then I find he’s not, but we’ve just got to take it bit by bit. I’ve watched him running today; he looks well and is in really good condition."
