Leicester captain Ed Slater and England international Freddie Burns have both agreed new contracts with the Tigers.
Lock Slater, 27, made his 100th appearance for the club against Bath in November and guided them to their fifth Aviva Premiership win in six games this season at the weekend.
Burns was not a part of that victory over Worcester due to a broken jaw, but he has also pledged his future to Welford Road after moving in the summer of 2014 having accrued over 1,000 points with previous club Gloucester.
"Ed has made a massive contribution over the last six seasons as a Leicester Tigers player," director of rugby Richard Cockerill told www.leicestertigers.com.
"He is the club captain because he is an outstanding player and an important member of the first-team squad both on and off the field.
"We're very happy that he has agreed new terms beyond the end of this season and we look forward to seeing his continued influence on those around him as well as his development as a player in this environment.
"Ed is among the English-qualified players and leaders at the heart of the squad, which is extremely important to the culture of the club."
Fly-half Burns, who has represented England on five occasions, added that he is keen to add to the history of the Premiership's most-decorated club.
He said: "When I first came to Tigers last summer, I always thought of it as a long-term move for me, not a short-term fix, and I'm very happy to have agreed a new contract to stay.
"Leicester is a great club with a lot of history and hopefully this group of players can add some history of their own."
