Colin Calderwood has joined Aston Villa as assistant manager after the club agreed a compensation package with Brighton.
The Scot had been Chris Hughton's right-hand man at the Amex since arriving in 2015.
Brighton & Hove Albion confirmed today they had agreed a compensation package with Aston Villa shortly ahead of last night's match, allowing for Colin Calderwood's release from his notice period this weekend.
The club would like to thank Colin for his service since February 2015 and to wish him well for the future.
Brighton & Hove Albion will now look to finalise its recruitment process for a new assistant manager.
Brighton manager Chris Hughton has signed a new four-year contract just days after the club missed out on promotion to the Barclays Premier League.
A draw at Middlesbrough on the final day of the regular league season saw Brighton condemned to third place in the Sky Bet Championship, when automatic promotion was tantalisingly close.
A painful play-off semi-final defeat followed at the hands of Sheffield Wednesday, meaning Brighton must try again next season to earn a place in the top flight.
And the ambitious Seagulls board members trust Hughton to lead the challenge, handing him a new deal that runs until 2020.
Brighton chairman Tony Bloom told the club's official website: "Chris thoroughly deserves this new contract after such an outstanding season.
"There is no doubt he is one of the best and most skilful managers in the country and we are delighted to be going into next season with Chris at the helm and leading our club, as we aim to go one step further and realise our ultimate aim of reaching the Premier League."
Brighton boss Chris Hughton felt striker James Wilson produced his "best all round 90 minutes" for the Seagulls as the Manchester United loanee hit the only goal in their 1-0 home victory over Reading.
Albion's fifth win in their last six home games lifted them into second place in the Championship and an automatic promotion place and Hughton felt Wilson fully justified his recall to the team.
Wilson partnered Sam Baldock up front with Israeli international Tomer Hemed dropped to the bench.
I wanted to play James. It was a question of who I played alongside him.
Bobby Zamora was not available through injury and I thought maybe Sam would complement James a bit better.
James has bit stop-start since joining us, but he has been involved and he's getting used to the level of what the Championship is.
It was a good, fast attack that led to the goal and it was James' best all round 90 minutes for us.
James Wilson netted a first-half winner as Brighton moved up to second place in the Championship following a 1-0 victory over Reading.
Albion, who now boast five successive clean sheets, survived a late rally from the Royals to record their first league win over the Berkshire side in 12 attempts.
The Seagulls have now won five of their last six home games and Reading's defeat still leaves them without a clean sheet away from home for six months.
Wolves clinched their third consecutive victory as a first-half own goal by Connor Goldson gifted them a 1-0 win over faltering Brighton.Read the full story ›

Striker Bobby Zamora has joined Brighton for a second time - 15 years after beginning his first spell with Albion.
The 34-year-old former England international was a free agent after leaving QPR and has signed a one-year deal, Brighton announced on Monday evening.
Young players on the books of Brighton and Hove Albion will be given sexual consent training.
All young male and female footballers at the Championship club will receive guidance on the law as part of the Protect, Inform and Prevent programme, the BBC said.
A former police officer and psychotherapist will give the training, which will provide a confidential environment to discuss previous encounters and explain when consent can legally be given.
Former Sheffield United striker Ched Evans was convicted of rape in 2012, an incident over which he protests his innocence. Evans tried but failed to return to football in the winter transfer window after serving half his sentence, but was unable to tie down a deal with Oldham due to the circumstances surrounding his conviction.
In 2013, four Brighton players were found not guilty of sexual assault and voyeurism after a 19-year-old woman claimed to have been assaulted at a hotel two years previously.
Brighton have been hit with a £90,000 fine by the Football Association and warned over their future conduct for admitting breaches of the governing body's agent regulations.
The charges relate to the Seagulls' acquisition of midfielder Dale Stephens from fellow Championship side Charlton at the end of January 2014.
Three authorised agents have also been sanctioned and warned to their future conduct for their roles in the same case.
In explaining the decisions, the regulatory commission decreed Brighton had "in the events which have happened, benefited from the non-payment of most of the commission".
It was revealed the south-coast club were charged under rule C.2, which states that a club "must not so arrange matters as to conceal or misrepresent the reality and/or substance of any matters in relation to a transaction or contract negotiations"
