The young winger has returned to parent club West Ham United, with Cherries attempts to retain his services proving unsuccessful.
Manager Eddie Howe is now facing a selection dilemma ahead of Rochdales visit to Dean Court this weekend, with his alternatives for the left midfield berth few and far between.
Anthony has gone back and the Football League have not allowed us to extend the loan at this moment in time, said Howe.
Were disappointed to lose him because it leaves us very short of options on the left-hand side of midfield.
Popular star Mark Molesley will probably get the nod, although he is not fully fit and is playing through the pain of a foot injury, which will eventually require surgery.
Veteran playmaker Sammy Igoe would be another possibility, but he is yet to overcome a persistent knee injury.
All of which leaves Howe with a tough decision to make as he casts an eye over his depleted resources.
He told the Echo: Mark Molesley has played the past two games on the left but, as everyone knows, Mark is playing through the pain barrier and making himself available to us even though he needs an operation.
At this moment in time, were just having to see how long Mark can keep himself going before eventually needing to go under the knife.
Hes done ever so well to put himself up for selection and to battle through because, if he was not available to me, we wouldnt have a replacement for him and wed have to play someone out of position.
Sammys not ready yet hes close but just cant seem to get 100 per cent right. Hes still feeling sharp pains in his knee and until they abate he wont be available for selection.
You can either go one of two ways. You can put someone there whos not a left midfielder.
Brett (Pitman) can do it hes one option. Anton (Robinson) has played in various positions for us and hes very versatile.
Or you can look to change formation and go without a left midfielder, but thats not really a road I want to go down.
