The 27-year-old has played only twice so far this season, due to injury problems.
“He’s (Palacios) trained with us over the last couple of days and I just think he needs a mini pre-season to get himself up and running. That’s all he’s lacking,” said Pulis.
“We’re trying to get him fully fit as soon as possible, but he’s already shown in training what he’s capable of doing.”
