The Saints hooker has been ruled out of the remainder of the Six Nations after being forced to go under the knife.
Hartley is expected to be out of action for at least four weeks but, all being well, the Red Rose co-skipper should be fit for England's World Cup squad for the tournament in Japan later this year.
Boyd is upbeat about Hartley's recovery and feels it could have been much worse news for England had the surgery been needed before the major tournament in September.
"He wants to be playing footy and he will be playing as soon as he can," Boyd told BBC Northampton. "The next little bit after the Six Nations, there isn't a lot on for England, so by the time the next little block of England stuff comes, I am pretty certain he will be fit and firing and as hungry as ever.
"From an England point of view, it's not bad timing really."
