Scottish defender Louis Jackson could be in Manchester United's FA Cup matchday squad today.
Jackson is in United's traveling squad due to injury concerns, reports the Manchester Evening News' Samuel Luckhurst.
The 18 year-old defender has made 15 appearances for the U18s and has played a further six games for the U21s in Premier League 2.
Harry Maguire is United's only fit senior centre-half, with Willy Kambwala not traveling to London for the clash with Coventry City.
Midfielders Mason Mount and Sofyan Amrabat are also unavailable.
