The 21-year-old midfielder missed the 1-0 victory over Krasnodar last time out in the competition, but he is back in contention for the trip to North London.
However, only two of Franjic's seven appearances in the Europa League this season have been starts, so he may have to settle for a place among the subs.
Sadegh Moharrami is the Croatian champions' only known injury absentee, the right-back having not played since the end of January.
That should mean Stefan Ristovski once again operating on the right side of defence in what is expected to be a 4-3-2-1 formation of sorts.
Indeed, visiting boss Zoran Mamic may well go with the same starting lineup from the win over Krasnodar last month.
Dinamo Zagreb possible starting lineup: Livakovic; Ristovski, Lauritsen, Theophile-Catherine, Gvardiol; Ivanusec, Jakic, Orsic; Ademi, Majer; Petkovic
