Crystal Palace boss Oliver Glasner says striker Jean-Philippe Mateta does not require surgery on his knee.
The Frenchman's move to AC Milan fell through on Deadline Day because the club doctors believed he needed to have an operation.
However, there was a difference of opinion from several specialists that Mateta has seen since the transfer window closed, according to Glasner.
"He doesn't need surgery," said the Palace boss, confirming it was Mateta that took the final decision.
"The injury is not as bad as feared. That is the opinion from several doctors and specialists that we can deal with the knee in a better way than with surgery.
"He will miss a certain [amount of] time. I can't say two weeks, three weeks, four weeks, but he doesn't need surgery. That's very positive. Hopefully, he is back soon."
Glasner said Mateta was disappointed his move to Milan collapsed at the last minute but expects the striker to benefit from having clarity over his future.
"It is clear now that he will be a Palace player until at least the summer," said Glasner.
"He wants to be back as soon as possible and contribute to achieve our goals. That is his mindset and it's the best he can do."
