Pompey wait on Ben Haim
Portsmouth defender Tal Ben Haim is a doubt for the visit of Millwall.
The Israel international missed Saturday's dramatic 2-2 derby draw at Southampton with a calf injury and is still struggling.
Midfielder Joel Ward replaced Ben Haim at right-back while another positional change saw Greg Halford step into midfield with Ricardo Rocha recalled to the defence at centre-half.
Halford was pushed further up as youngster George Thorne has returned to West Brom after his loan spell, and his season, were cut short by an ankle injury.
Out-of-favour Forward Dave Kitson will hope to be involved again after making his first appearance in a month as a substitute at St Mary's.
Defender Aaron Mokoena (ankle) and striker Kanu (back) still are out.
