As a result, both strikers will miss Saturday's Barclays Premier League encounter with Swansea City at Old Trafford, although the boss is optimistic that Rooney will return from overseas to face old foes Chelsea at Stamford Bridge on Sunday 19 January.
“Well, with Wayne we've sent him away on a hot-weather break," Moyes told reporters during his pre-match press conference at the Aon Training Complex. "His groin isn't quite recovered yet so we've sent the fitness coach with him and he's away with his family. It will give Wayne a bit of break.
“We always hoped to be able to do it at some time in the season and the groin is not as good as we'd hoped. Hopefully we can get him fit for [the] Chelsea [match] but we'll see how he is. He's away and will do some work with the fitness coach.
"Robin is going to be a little while. We'll do everything we can to get him back quickly. Wayne has got an injury and we have to hope for that, but we'll see how it goes. It's probably the right time to give it a chance to heal. We thought the best thing was to get him to the warmer weather with one of the coaches and spend time with the family as well. Hopefully it will make him better."
