The Forest loanee looked like being out for the rest of the season.
The Portuguese star is struggling with a groin injury and it was confirmed by recently sacked boss Dougie Freedman to BBC Nottingham Sport in mid-March that Oliveira looked likely to miss the rest of the season and would not play for Forest again.
TSF Radio Noticias then reported that the groin injury was worse than feared and that Oliveira was definitely out of contention for the European Championships and that he was back at parent club Benfica receiving treatment.
But it seems he has recovered faster than first expected.
Speaking to BBC Nottingham Sport this week Forest player turned coach Andy Reid has confirmed that the forward has been back at the club but would not state whether he was in contention to feature in the final games of the season:
“We are just monitoring it as we go along. It wouldn’t be fair on the player or the players in the squad at the moment if we were to say one way or the other. So we’re just going to monitor him.
“He got a groin injury and he has been back in and been around the place. We are just going to see how that one goes.
“It is (encouraging). It’s good to have him back around the place. He has been good for us since he’s been at the club so we’re pleased to have him back around, so that’s nice.”
The striker has been in fantastic form for Nottingham Forest this season. He has scored nine goals in 29 games for the club in an excellent loan campaign at the City Ground.
Forest fans will therefore be hoping that Oliveira can make it back into the first-team to play some part in the final five games of the season, as the club look to end a six game winless streak.
