Millwall striker John Marquis will have his loan deal at Portsmouth extended by another month.

The 21-year-old's initial four-week spell with Pompey came to an end following Saturday's 1-0 win over Bury, but manager Guy Whittingham confirmed after the match that an extension had been agreed.

Marquis, who has scored two goals in five matches since moving to Fratton Park, will now be available for Tuesday night's visit of Wycombe.
