The Brentford medical team are currently nursing 11 injured players back to health ahead of their Premier League London derby against Arsenal at the Gtech Community Stadium on New Year's Day.
The Bees lost both Mark Flekken and Ben Mee to unspecified concerns in their 0-0 draw with Brighton & Hove Albion on December 27; the latter is out of this game, but Frank is hopeful that Flekken will play.
Mathias Jensen (calf) and Sepp van den Berg (groin) are expected to be back in the squad too, but Igor Thiago (knee), Gustavo Nunes (back), Rico Henry (knee), Aaron Hickey (thigh), Josh Dasilva (knee), Kristoffer Ajer (ankle) and Ethan Pinnock (thigh) will definitely miss out.
If Flekken is unable to shake off the problem that forced him off in the first half at the Amex, Hakon Valdimarsson will make his full Premier League debut, but there is seemingly a good chance that the Dutchman will be OK.
Frank will also have no choice but to throw 20-year-old centre-back Kim Ji-soo into the deep end if Van den Berg and Mee are not given the green light, but Nathan Collins, Mads Roerslev and Keane Lewis-Potter are fit and raring to go.
Amid all the defensive uncertainty, the hosts can line up with an unchanged double pivot of Christian Norgaard and Vitaly Janelt, who will operate just behind creative fulcrum Mikkel Damsgaard.
No alterations should be considered up top either, where Kevin Schade and Yoane Wissa will work in tandem with Bryan Mbeumo, who has struck 12 goals and provided two assists in his last 15 Premier League London derbies.
Brentford possible starting lineup:
Flekken; Roerslev, Collins, Van den Berg, Lewis-Potter; Janelt, Norgaard; Mbeumo, Damsgaard, Schade; Wissa
