Harry Maguire should be available for Manchester United's crucial Europa League quarter-final first leg at Lyon on Thursday.
The experienced centre-back was withdrawn in the 58th minute of the 0-0 draw with Manchester City, with Victor Lindelof taking his place at the heart of the back three.
Although Amorim had admitted before kick-off that Maguire's minutes were being managed and he may not play the full game, the 32-year-old did move a little uneasily when making his way to the touchline.
It sparked fears among some fans that the defender could be a doubt for the game in France, particularly as Matthijs de Ligt was forced out of the derby with an issue he picked up during the 1-0 defeat at Nottingham Forest.
