"Rio has been training very well in the last few weeks. He will play tomorrow," Ferguson told reporters at his Friday press conference.
"This is the time to bring him back," Sir Alex added.
"We have gone through the whole situation with him in terms of enough training and endurance work.
"It is a big boost because the defence has been the weakest part of our game this season.
"At various times we have lost Ferdinand, Nemanja Vidic, Edwin Van Der Sar, John O'Shea.
"It has been a rough time, so to get them back can only be good for us."
This is fantastic news, especially when you consider that yesterday Sir Alex Ferguson was confirming that John O’Shea was out for the rest of the season.
