Tierney was named to start at corner forward last week but was replaced by Padraig McMahon on the day and he finished the game as an unused substitute.
His tweet was criticised on The Sunday Game by pundit Kevin McStay who said inter-county GAA players shouldn’t air their grievances on Twitter. However, Tierney has reacted angrily to the message being discussed on national television.
“The reality of it is that’s my private life,” said Tierney. “I know Twitter is a public forum but you need to follow me to read my tweets and Des Cahill follows me.
“Why bother bringing it up? They were making something out of nothing. It says more about the quality of The Sunday Game that they have to talk about a tweet by me.
“That’s the stupidest part of it. Obviously, they haven’t much to be talking about and that’s the truth of it.”
Tierney insists his message wasn’t directed at Laois manager Justin McNulty for not selecting him to start the game.
“It wasn’t a dig at management,” he maintained. “A lot of people have taken it that way but that is not the case.
“I was disappointed. I felt I had played reasonably well in the league and not to be in the five subs that came on was disappointing.
“I put the message up when I was listening to music on the way home from the match. I also put it on Facebook and there wasn’t half as much said about it but that’s because Facebook is private.
“Somebody wrote in a newspaper that players should follow the GAA guidelines for the social media but we would have to be paid for that to happen.”
Also on Twitter on Sunday evening, Tierney had a conversation with Mayo’s Conor Mortimer in which he explained he had no idea why he was omitted from the team.
“Your guess is as good as mine,” he wrote in response to Mortimer’s question.
Tierney told the Irish Examiner: “Conor asked me why it was strange I hadn’t started and I told him my point of view.
“I respect the manager’s position. He had a reason for making that decision and had we won it would have looked even better.
“On the way to the game I had people phoning me that I had been dropped off the panel.
“I put them right and told (them) it was false but again after the game I was getting phone calls asking me had I been dropped but that’s not true.
“The message was what it was. I thought I would have got on. I’m GAA to the core. I love playing. I love training. I love Laois. I live, breath and sleep GAA.”
Tierney hasn’t yet spoken with McNulty since he put up the messages on Twitter.
“We had a word in a team talk after the game. He spoke about doing a bit of soul searching and coming back to training on Tuesday evening.
“We have a lot of work to do before the qualifiers. We thought we were further ahead than we actually were.”
