Derek McInnes has been speaking to the media before Hearts visit Motherwell in the Premiership this weekend.
Here are the key lines from the Tynecastle boss:
Lawrence Shankland should be available after a calf problem but record signing Ageu faces a further spell on the sidelines after scans revealed a torn hamstring.
McInnes said: "It's in a slightly different area to the original hamstring [injury] and he's due to see a specialist tonight."
The Hearts boss is hopeful Stuart Findlay will also be fit after going off with an ankle problem in last weekend's loss to Aberdeen.
Hearts will investigate the reasons for so many hamstring injuries, which have deprived them of Beni Baningime, Calum Nieuwenhof, Ageu and Finlay Pollock for chunks of the season.
McInnes adds: "I think it would be remiss or wrong for us not to look at this a lot more in depth. Muscle injuries, when players are that fast-twitch, and they're so athletically tuned. Everyone's a bit different. The four hamstring injuries that were mentioned, they're all in different areas."
Hearts were the "better team" at Pittodrie and only have "ourselves to blame" for suffering a first defeat of the season.
McInnes detects "no hangover" from that loss after having an "honest assessment" with the players of what went wrong.
The squad is now being "tested" with injuries but McInnes says: "It's a long season. You're going to have to deal with that... These boys have shown enough up until now. The league table doesn't lie. They've shown enough up until now that there's enough encouragement there that we can get results with the squad we've got."
He is delighted the club have sold out their 4,800 allocation for Saturday's game and adds: "I think we've sold out at Falkirk already. We've sold out at Celtic Park already. It shows you the buy-in for the supporters."
On suggestions Hearts' bubble has burst: "I don't really care too much about that. As a manager, you're always looking for your reaction to a disappointment. I think I know my players. I know they're conscientious. They're real. They're authentic. We know they care. Obviously, when you lose a game of football, it's not nice. But the response will be there."
