Prop forward Fraser Balmain has become the third player to agree a new deal with Leicester Tigers this week.
The 23-year-old tighthead has progressed through the youth set-up and is closing in on 50 appearances.
Balmain has started nine games this season, with six as a replacement.
"Fraser has been doing a good job, especially this season when we have been without some of our more senior players in the forward pack," said director of rugby Richard Cockerill.
"He is improving all the time and, as a prop, he still has time on his side to continue that improvement."
Fly-half Owen Williams and lock Graham Kitchener have also agreed new contracts.
