Jonny Williams is reportedly a target for south London neighbours Charlton and fellow midfielder Adlene Guedioura has been linked with a return to Nottingham Forest.
However, Pulis is mindful not to leave himself short for the rest of the season, with a busy fixture schedule on the horizon after the postponement of their recent trip to Everton.
“I’ll sit down and look at things,” he said.
“We are close to sorting out the Everton fixture which will give us a three-game week, which is very difficult for clubs who have just come up to the Premier League.
“We’ll look at it and then take a view.”
One player Pulis is desperate to get into his team is Glenn Murray, who made his comeback after 10 months out with a cruciate injury as a substitute against West Brom a fortnight ago.
Murray’s 31 goals last season helped fire Palace to promotion and Pulis feels the striker is capable of helping them stay there.
“Glenn’s got another week of training under his belt, he’s worked hard and trained really well,” added Pulis.
“He’s a natural goalscorer, he scored 30-odd goals last year before he got injured so we are desperate to get him back in the team.”
Murray is likely to be on the bench again when Palace host Manchester United on Saturday.
Port Vale boss Neil Aspin is expected to choose from an unchanged squad for the home game against Exeter.
