Crystal Palace defenders Damien Delaney and Joel Ward have yet to agree new deals at the club.
Blackpool are considering offering terms to Jonathan Legear, with it up to the Belgian midfielder to prove his fitness.
Reading manager Nigel Adkins insists the club will not be forced into selling players following their relegation from the Barclays Premier League.
The Royals will seek an immediate return to the top flight next season after last weekend's goalless draw with QPR condemned them to a year in the npower Championship.
Russian striker Pavel Pogrebnyak is among the players tipped to leave the Madejski Stadium, but Adkins insists Reading will determine what happens in the transfer window.
"We will want to do the business we want to do, that's the important message," he said.
"Yes we will be in the Championship next season, but this is a well run club and whatever business we do is because we want to.
"Like every club you cut your cloth accordingly and players who were on Premier League wages won't be on them in the Championship, which is prudent business.
"We want to be successful and we are ambitious. If players leave, it's because we'll allowed them to make leave.
"It will be our decision, it's our business and we don't have to sell."
Reading have three matches left this season - starting against Fulham on Saturday - but Adkins revealed that planning for next term is already under way.
"Now that we know what division we're in next season we're able to establish some processes to move this club forward," he said.
"Conversations have been going on, but they'll remain private and confidential.
"What is important is that we give ourselves the chance to get back in the Premier League because it's the competition everyone wants to be in.
"This club has always been run prudently and that's important. Good conversations have been had with the owner and there's a lot of ambition at this club.
"What we must do is keep building on the successes of the past, because the last 10 years have been very successful in the history of the club.
"The greatest lesson we've learned this season is that we must keep moving forward. You must keep evolving and build on your successes."
