The striking duo both pulled out of midweek internationals for England and Holland respectively but it does not seem the damage is too bad in either case.
"There is a doubt about Wayne, but Robin should be fit," United boss Sir Alex Ferguson said.
Ferguson also confirmed Jonny Evans was doubtful for the Carrow Road encounter with a groin injury. However, the United boss had good news on Phil Jones.
The England defender has not played for the Red Devils this term after suffering a knee injury during pre-season.
Jones is closing in on a return, though, which could come against Galatasaray in the Champions League on Tuesday.
"Phil has been training all week," said Ferguson. "We will take him to Turkey. That is a great start for him."
Ferguson also re-stated his intention to hand Javier Hernandez a start after his match-winning cameo at Aston Villa last week.
"Javier came on last week and changed the game completely," said Ferguson.
"He should start tomorrow."
