Morgan missed the 1-0 defeat to Blackpool last weekend as he was ill but he is back to full health and is expected to return to the starting line-up.
Manager Gary Johnson has plenty of other selection problems to contend with, however, as two relegated sides face up to each other.
Goalkeeper Joe Lewis is struggling with a hip injury so James McKeown is on standby to continue while left-back Scott Griffiths is also a doubt with a stomach injury.
Strikers Aaron Mclean (knee) and Izale McLeod (knee) are out along with winger Chris Whelpdale (ankle) and defender Gabriel Zakuani (groin).
Midfielders Lee Frecklington (hamstring) and Sergio Torres (ankle) are also on the sidelines.
The match kicks off at 1pm.
