At the club's midweek media session, Davies was asked for an update on both players.
"Ryan Mills has fractured his fifth metatarsal in his left foot. He's had surgery, it's been pinned back and he will be out for between six and ten weeks.
"Sinbad's injury is obviously a little bit more serious. He's dislocated and fractured his left ankle, and that will be anything between four to sixth months.
"It's early stages, but obviously it was a severe injury with quite a lot of damage there. But the surgeon is pleased with the results of the operation and it's now all about the rehabilitation over the forthcoming months and we'll see how quickly we can get him back."
Losing two players is never good news at the best of times, but Davies admitted the frustration is greater given that both have been in good form of late.
"They've both performed very well. Ryan, in particular, in terms of coming back from a long term injury himself, it's been great to see him get a run of games.
"He's been going exceptionally well, he's a lovely ball playing 12 and has been able to bring other players into the game. He's made a significant impact upon our performances.
"And we all know what James can do. He's a fantastic player.
"It's disappointing for the pair of them as individuals, and for us as a group. But that's where we are, and we have to get on with things."
