You can't realistically count Dunne as a possible starter, given how long he's been out and the questions over whether he'll ever play for us again. You'd be as well using Tait or Hartley's absences as an excuse.
We're probably missing Donnelly more than anyone, but the club knew how long he'd be out, so why the hell didn't they prioritise finding a replacement long before January's window opened? We managed to bring Kelly in on relatively short notice, so it can be done. Somebody has to answer for the mob we did recruit, because the few who are available are undoubtedly useless in our current situation.
