Championship strugglers Millwall are likely to be without defender Danny Shittu for the rest of the season.
The 33-year-old centre-back, who has made 23 appearances this campaign, sustained an Achilles injury in the 1-0 win at Derby County on 8 March.
"By the time Danny is due to recover he will be short of match fitness," Lions physio Bobby Bacic said.
"He is in a protective boot for another three weeks so he is limited in the specific fitness work he can do."
He added: "Even when he comes out of the boot he will be doing low-level loading for the following two weeks.
"Danny will effectively be ruled out for the rest of the season."
