The 23-year-old was forced off in Wolves’ win over Charlton on Saturday.
Dicko is set to have an operation next week.
Kenny Jackett has confirmed the club is looking to strengthen their attack due to Dicko’s injury.
“We are still looking and trying for something before Tuesday but that may be difficult,” he told the Wolverhampton Express & Star.
“If it doesn’t happen, we will continue to look at the loan market and then again in January.”
