Leicester Tigers followed up the weekend derby win over Northampton by tying Adam Thompstone, Matt Smith and Telusa Veainu to new contracts.
The trio started Saturday's 30-27 victory over Saints, with long-serving Smith scoring the first of Tigers' three tries.
He is currently in his 11th year in the Leicester first-team, having matched his father Ian in making 100 starts for the club during the 2012-13 season.
Tigers director of rugby Richard Cockerill said: "Matt has been a fantastic servant of the club and to have players who have such a strong link with Leicester, following their dad into the team, is very important here.
"He's been in outstanding form for us this season, his attitude to his work is first class and that is the kind of influence you want in the squad."
Veainu joined Tigers after playing for Tonga during the 2015 Rugby World Cup, and described his past year as a "whirlwind".
Thompstone, meanwhile, joined Leicester from London Irish in 2012 and has gone on to score 18 tries for the Welford Road club.
He said: "I'm enjoying my rugby and we've made a pretty decent start to the season in the league and in Europe.
"We have a very talented group of boys in the backline, we're playing some good rugby and I want to be part of that going forward and trying to contribute as much as I can."
