Bolton full-back Marcos Alonso will be out for four to six weeks after suffering an injury setback.
Manager Owen Coyle confirmed the 20-year-old will have surgery to replace a pin that was initially inserted after he broke his metatarsal in August.
Alonso limped off as Bolton eased their relegation worries with a 2-1 win at Blackburn on Tuesday.
Coyle said: "There was no new fracture. When he comes back he'll be able to kick on with his career."
The Spaniard was only making his third appearance of the season at Ewood Park, but Coyle was relieved the player did not suffer a repeat break.
"The pin they put in when they did the operation to heal the original fracture took a hit and needs to be replaced so he could be out anything up to six weeks but we're hoping for earlier than that," said the manager.
"The operation will happen today (Friday and we'll take it from there. He came in for the Fulham game the other night and looked assured and destined for a big future.
"I said to him he can handle the level and be comfortable in the environment."
The former Real Madrid player initially fractured his foot in his side's 2-1 Carling Cup victory over Macclesfield Town in August.
Alonso made his first Premier League start of the season during last Saturday's 2-0 defeat at Fulham.
