Derry manager Damian McErlain has been dealt another blow ahead of their championship opener with Tyrone.
Lavey half-back Eamon McGill sustained a broken wrist in their win over Coleraine on Sunday.
McGill starred on the run to last year's county final and was called into the county squad.
He started five of Derry's seven league games and came on as a sub in the final against Leitrim.
It is another defensive loss after Michael McEvoy's decision to spend the summer in America.
Lavey duo Declan Hughes and Niall Toner are also due to go travelling and are out of contention.
Former minor captain and U20 winner Shea Downey hasn't featured this season. He has been struggling with a hamstring injury and was substituted in Lavey's last two league games.
Ballinascreen's Benny Heron picked up a shoulder injury against Bellaghy and missed their defeat to Magherafelt.
The recently wed Heron returned to the panel late this year, making his first appearance in their round seven win over Wexford.
On the plus side, Ciaran McFaul played in all four of Glen's league games after missing the latter stages of Derry's league campaign with hamstring injury.
Also in the mix are Coleraine duo Ruairi Mooney and Liam McGoldrick.
As planned, the pair went travelling after Coleraine's defeat to Scotstown and returned for the latter stages of the national league but didn't see any game time.
U20 winning captain Conor Doherty picked up a hamstring injury in Newbridge's first league game of the season but returned to score two points in Sunday's round four win over Drumsurn.
