Tigers trio extends stay
Peterborough-born Wells played in all six games in the successful Anglo-Welsh Cup campaign this season as well as making his first start in the Premiership in an away win over Harlequins at the end of February.
"I've played a lot more rugby this year and I'm happy to get a new contact here. It's a good group of players to be involved with and I try to pick up as much as I can learning from the coaches and the experienced players around me.
"I've enjoyed it so far this season and I just want to keep developing my game and putting myself forward," Wells said.
Former England international Tait recently passed 100 appearances for the club – since his Tigers debut in 2011 – and he captained the team to victory in the Anglo-Welsh Cup Final in March 2017 as the club collected its first silverware in four years.
"I'm delighted to agree a new contract. I just want to keep contributing to the club.
"I've thoroughly enjoyed my time here, Tigers is a massive club and playing in big games is one of the main reasons you want to be here. I'm very glad to be doing that," Tait said.
Rizzo has returned from injury to take his place in the Tigers front row in the second half of the 2016/17 season and was part of the Anglo-Welsh Cup Final squad with victory over Exeter Chiefs.
The form of the 34-year-old Rizzo also earned him a recall to the Italy squad during the 2017 Six Nations and he now has 23 Test caps.
"I have agreed another contract and it is great to stay with the club. It is a privilege for me to play for the Leicester Tigers and from the first moment I joined I thought Leicester felt like home," Rizzo said.
