Chris Hughton indicated he would make changes to his team on Tuesday night.
However, still a surprise to see the Brighton boss play an entire reserve side.
Brighton faced Bournemouth on Tuesday night, five days ahead of the Premier League game against Newcastle.
Talking about injuries and the demands on his squad before the game, Chris Hughton had made clear he would be keeping players back for the priority of the league game.
In the event, only 33 year old squad player Liam Rosenior stayed in the team.
Brighton lost 2-1 at Bournemouth in the Premier League on Friday night and 10 changes were made as the two teams played each other at the same venue in the League Cup.
Tim Krul made his debut for Brighton despite not even getting a place on the bench in the league matches so far.
The on-loan Newcastle keeper performed heroics as Bournemouth battered the Brighton second team with 14 corners and 29 shots – nine of them on target.
Tim Krul was eventually beaten nine minutes into extra time after the 90 minutes ended goalless, Joshua King getting what turned out to be the winner.
Krul was almost the last gasp saviour when going up for a corner in the final seconds of extra time, the ball falling for him in the box and his shot going past the left hand post.
The League Cup is a distant memory already for Newcastle fans having exited at the first attempt, with then three Premier League wins on the bounce easing/erasing any disappointment.
A gamble by Chris Hughton and a chance that as well as dropping out of the cup after playing a reserve side, Brighton could drop into the relegation zone if losing to Newcastle on Sunday.
