Morrison joined the Terriers on loan in January and went on to make 22 appearances, playing an integral part in the club's landmark season.
But the 21-year-old has now returned to the Premier League new boys, despite having made just one appearance in the League Cup since his arrival from Swindon Town 18 months ago.
And if Morrison is not going to be involved in Brian McDermott's plans next season, Huddersfield would be happy to offer the centre-half a return to the Galpharm Stadium.
"Sean has made it clear he loves it here and would like to play for us in the championship and we certainly love him, so we'll see what happens," Terriers coach Glyn Snodin said.
"In the first instance it's very much down to what Brian McDermott, the Reading manager, wants to do.
"Does he want to keep Sean for the top-flight campaign, does he want to sell him or is he prepared to loan him out again?
"Until we know the answer to those questions then we can't really progress anything, but we know Brian very well.
"He is a smashing fellow and we know there won't be any problems, he will just let us know honestly exactly where he stands."
