Munroe, 24, played in all but one of Tyrone's league but failed to nail down a regular starting place.
He started the season-opener against Roscommon and was a substitute in five other Division One games.
The combative defender, who has pace and skill, appeared ideally suited to Tyrone's style of play.
Munroe will now devote all his energies to his club for the remainder of the season, good news for Carrickmore, who will have full access to their top player.
The Carrickmore club now has no representatives in the Tyrone squad.

Speaking at London's Science Museum the scientist also says he believes the future of humanity depends on living on other planets.
"The long-term future of the human race must be space and that it represents an important life insurance for our future survival," he says.
"It could prevent the disappearance of humanity by the colonisation of other planets."
Professor Hawking made the comments while escorting an American visitor around the museum as part of a guest of honour prize.
"Sending humans to the moon changed the future of the human race in ways that we don't yet understand," he went on.
"It hasn't solved any of our immediate problems on planet Earth, but it has given us new perspectives on them and caused us to look both outward and inward."
Adaeze Uyanwah, 24 and from California, won the tour after producing a blog and video describing a "perfect day" in London.
She asked Prof Hawking what human failings he would alter.
"The human failing I would most like to correct is aggression," he says.
"It may have had survival advantage in caveman days, to get more food, territory, or partner with whom to reproduce, but now it threatens to destroy us all.
"A major nuclear war would be the end of civilization, and maybe the end of the human race."
The scientist then got a bit spiritual when he told her: "The quality I would most like to magnify is empathy. It brings us together in a peaceful, loving state."
Ms Uyanwah says she was blown away by the meeting.
"It's incredible to think when my grandchildren are learning Stephen Hawking's theories in science class, I'll be able to tell them I had a personal meeting with him.
"It's something I'll never forget."

RGU said a downturn in the regional economy due to the falling oil price had affected the university's income.
It also reported a reduction in demand for courses from students from oil-producing countries.
RGU said the aim was for the savings to be made through a voluntary redundancy scheme.
Prof Ferdinand von Prondzynski, principal of the university, said: "RGU will embark on a period of re-profiling its workforce to address the financial challenges and our strategic needs, allowing us to pursue ambitious targets for the successful, sustainable development of the university.
"We will continue to make a leading contribution to economic growth here and across Scotland, widening access to higher education, and the availability of high value knowledge and skills for the economy and society."
An additional £2m of savings are to be made via operational costs.
Tyrone defender Johnny Munroe has left the squad, and will play no part in the county's bid to retain the Ulster Football Championship title.
