The young midfielder - still only 19 - made his league debut for Coca-Cola League One side Chesterfield and played the full 90 minutes in a 1-1 draw at Doncaster Rovers.
Reserve team regular Jamie hooked up with the Derbyshire club on a three-month loan arrangement last Friday and was thrown straight in at the deep end the next day.
Ã¢â‚¬Å“It was great to go straight into the team and get on with it,Ã¢â‚¬Â reflected Jamie. Ã¢â‚¬Å“It was hard but I enjoyed it.
Ã¢â‚¬Å“The game was a lot quicker than I expected. I had a few big tackles in the first 10 minutes and that woke me up to it.
Ã¢â‚¬Å“I thought IÃ¢â‚¬â„¢d play my way into the game for the first five minutes but my first three touches were crunching tackles. I wasnÃ¢â‚¬â„¢t going to back out though.
Ã¢â‚¬Å“It was an ideal start, a crowd of over 6,000 and Doncaster are a good side. They really came at us and didnÃ¢â‚¬â„¢t stop - I thought to myself Ã¢â‚¬Ëœthis has got to slow downÃ¢â‚¬â„¢ but it carried on at that pace for the full 90 minutes.
Ã¢â‚¬Å“I managed to get my foot on the ball a few times, got some good crosses in and tried to pass it around when I got the chance. I thoroughly enjoyed it.Ã¢â‚¬Â
Jamie earned positive reviews on his debut as the Spireites - managed by former Derby and Bolton boss Roy McFarland - came from 1-0 down to stretch their unbeaten record to 12 matches and go sixth in the table.
Ã¢â‚¬Å“I delighted the loan has happened,Ã¢â‚¬Â added Jamie. Ã¢â‚¬Å“IÃ¢â‚¬â„¢m still young but I feel IÃ¢â‚¬â„¢m ready for the step up and hopefully going to Chesterfield will make me a better player and when I come back IÃ¢â‚¬â„¢ll be that much closer to the first team.
Ã¢â‚¬Å“ItÃ¢â‚¬â„¢s a different ball game. These lads are playing to pay their mortgage - itÃ¢â‚¬â„¢s the real thing. The physical side of it, having to win tackles, headers, you canÃ¢â‚¬â„¢t let your team-mates down in league football.Ã¢â‚¬Â
It took just a few minutes for Jamie OÃ¢â‚¬â„¢Hara to realise he was tasting the real thing in terms of competitive football at the weekend.
