Premier League Norwich City were on the end of the first shock on the opening day of the 2013 Hughes Insurance Foyle Cup.
Limavady United's under-15s marked the first Foyle Cup game to be played in the town – in honour of the 400th anniversary of the foundation of the town – by stunning the Canaries kids with a 1-0 victory.
And that result will boost the Roesiders confidence as they enter today's north-west derby against a Derry Select.
Institute's hopes of doing the same to Scottish Premier League Hibernian in the under-19 section were dashed as early as the 10th minute when the Edinburgh side took the lead at the Riverside Stadium.
A free-kick from Jordan Sinclair was swung in from the right wing and Jason Cummings was on hand to score from close range.
And Hibs were close to making in 2-0 within minutes, only for the Dutch officials to rule that Cody Mulhall was offside as he broke through on goal.
He didn't have to wait long for another opportunity though, firing a shot across Institute goalkeeper David McFaul to make it 2-0 with less than half an hour gone.
Dylan McClain shot over the bar on 32 minutes as Institute tried to get back into the game, but despite Corey Hegarty causing a few problems for the Scots' defence they remained two goals down at the break.
Stute grabbed a lifeline on the hour mark when Jaime Sproule pounced on a loose ball just outside the six yard box and fired it into the top corner of the net.
They then went in search of an equaliser, but were hit on the break in the closing minutes as Callum Crane completed a 3-1 win for Hibs.
Elsewhere in the under-19 section Ballycastle Youth, who were only brought into the tournament at the weekend, continued the trend of shock results when they beat Finn Harps 2-1.
And Cliftonville's under-15 team were the victims of an upset too when they lost 1-0 to Brandywell-based Ballymoor.
It wasn't just Hibernian's under-19s who beat a local team 3-1, their under-17s mirrored their older counterpart's result when they beat Derry City 3-1.
Derry's under-19s were in form though, beating Mountjoy United 7-0.
Lisburn Youth under-13s were the highest scorers of the opening day when they put eight goals past Ballymoney, without reply.
The big game in that section lived up to its billing in terms of excitement, but there were no goals between Sheffield United and Donegal Schools.
That shouldn't have been the case though as Donegal had chances to build an early lead.
James Carolan was guilty of a glaring miss from close range after only five minutes and Sheffield United goalkeeper, Hugo Warhurst then denied him minutes later after another strike, this time from distance.
Mark McAteer then found himself free on the edge of the Blades' box, but the Donegal midfielder pulled his shot wide.
After Reon Potts low cross flew across goal and wide of the far post for Sheffield United Joe McGill missed the best chance of the half for Donegal when he slipped when it looked like he was about to score after Warhurst parried a shot into his path.
Cameron Hawkes and Ben Harriot had chances for Sheffield United in the second half, but neither team could find the priceless breakthrough.
There were no such problems in front of goal for Glentoran in the under-13 section as they completed a 4-1 win over Coleraine, with Crusaders beating Ballymena United 2-0 in another Irish League encounter.
