Huddersfield have already stated that they would welcome Morrison back with open arms to the Galpharm Stadium.
"I'm sure he will have a few clubs come in for him - he's a brilliant young defender," Karacan told getreading.
"Sean knows it will be good to get back here with the squad. He loves the boys and the club and has always wanted to play for Reading.
"Whether he needs to go out on loan again, I guess time will tell, but I'm sure Reading fans will see a lot more of him in the future."
