MILLWALL boss Neil Harris is hoping his international contingent return to Calmont Road without any injuries this week.
Harris has already lost Shaun Williams for three months and Byron Webster for the season.
George Saville made his international debut in Northern Ireland's 3-1 defeat to Germany at Windsor Park on Thursday night.
Saville made his second appearance when he came on as a half-time substitute for Oliver Norwood in the 1-0 defeat to Norway on Sunday night.
Conor McLaughlin started as one of three centre-backs, while Shane Ferguson was a 79th-minute substitute.
Northern Ireland were guaranteed a place as one of the best eight second-placed teams before their loss in Oslo, after Scotland's 2-2 draw in Slovenia earlier in the evening.
Jordan Archer was on the bench in that game as Scotland's World Cup hopes were ended.
Aiden O'Brien is in Wales for the Republic of Ireland's crunch final Group D qualifying fixture, but he is unlikely to feature.
Harris said: "From a selfish perspective I hope all players come back fit and healthy this week. We'll have to be patient with that one.
"I hope they perform well and enjoy their time away.
"But first and foremost can they come back free from injury and ready to compete against Brentford."
