England internationals Dan Cole and Tom Youngs, and Argentinian International Marcos Ayerza have all signed new long-term contracts at Leicester Tigers.
Cole and Youngs both came through the Tigers academy, and Ayerza has been with the club since 2006.
Between them, they have made more than 400 club appearances and 120 Test caps.
Director of rugby Richard Cockerill said he was delighted the club have secured their signatures.
Leicester Tigers have announced England World Cup winner Ben Kay's appointment to the club's board of directors.
Former second-row forward Kay made 281 appearances for the Tigers between 1999 and his retirement four years ago, winning six league titles and back-to-back Heineken Cups.
And during a 62-cap England career he played in two World Cup finals, highlighted by the 2003 extra-time triumph against Australia in Sydney. Kay also made two Test appearances for the 2005 British and Irish Lions.
Leicester executive chairman, Peter Tom, said: "Ben brings with him the experience of more than 10 years as a Leicester player and as a rugby international.
"He has a deep knowledge of the professional game, and we look forward to his contribution as a Leicester director."
Leicester Tigers suffered a humiliating defeat at the hands of Bath, losing 45 - 0 in the Aviva Premiership.
Both sides were unbeaten going into the match, but it was Bath who emerged the clear winners, against a Tigers side who were without centres Manu Tuilagi and Anthony Allen. The pair were injured in the build-up to the match.
Leicester Tigers are leading Newcastle Falcons 12 - 3 at half time, courtesy of four penalties by Freddie Burns on his debut for the club.
Ed Slater will be Leicester Tigers' club captain for the 2014/15 season.
Slater made his debut with the Tigers four years ago after returning from Australia.
He is fast approaching 100 first team appearances for the club.
He succeeds Toby Flood.
Leicester Tigers' Vereniki Goneva has been crowned the 2014 players' player of the year at tonight's Rugby Players Association awards dinner.
Goneva scored 12 tries in his first season at Welford Road. The winger recently signed a new two-year contract with the Tigers.
"This means a lot and I'm really very happy. It's an honour to win this award because a lot of players have done very well this season."
"To be voted by other players is something very special. A lot of players fight for this award so to be recognised like this is great."
The coach of Northampton Saints Jim Mallinder has described last night's victory in the Aviva Premiership Semi-Final as 'absolutely tremendous', especially as his side lost to Tigers in last year's final.
"We've played Leicester numerous times since I've been here, we've won a couple but not recently and I think to win such a big game like that the semi final of the Aviva Premiership in front of our home fans was absolutely tremendous."
Speaking after defeat in the Aviva Premiership Semi-Final to Northampton Saints, Director of Rugby Richard Cockerill said:
"We gave everything, it's been tough year, we were close to winning we could've won it if we'd managed the game a bit better at times and our discipline had been a bit sharper but Saints are a good side, they played well, they took their opportunities and that's life"
Northampton Saints have beaten the Leicester Tigers 21-20 in the Rugby Union Premiership semi-final. It means the Saints will now play at Twickenham.
