Stoke insist they will not risk striker Mamady Sidibe's long-term health in a bid to get him fit for the end of the season.
The Mali international suffered a cruciate knee ligament injury while warming up prior to last week's reserve fixture against Aston Villa.
Pulis told the Stoke Sentinel: "The options are split between rest and recuperation on the one hand, in the hope the injury will settle down, or immediate surgery to repair the ligament."
He added: "The first course of action might mean he comes back in time for the last three or four games of the season, while the second obviously means a long period of recovery.
"We'll have a good discussion today to decide the best course of action but the bottom line is we do what is best for Mama.
"I think every fan knows what a lovely fella he is and he'd die for the cause but it will be a decision ruled by the head and not the heart."
Sidibe was out of action for two months earlier in the season with an injury to the same knee.
