Up-and-coming trio Jacob Blyth, James Pearson and George Taft have signed one-year contract extensions with Leicester, and academy scholar Rob Paratore has put pen to paper on his first professional deal.
All four players have featured heavily for Steve Beaglehole's table-topping Under-21 side this season, with second-year scholar Paratore, 18, also playing a key role in Trevor Peake's Under-18 set-up.
Development squad striker Blyth, 20, finished the season as top scorer for the Under-21s, as well as picking up loan experience with Burton and Notts County.
Pearson, 20, was also a regular in the development squad's successful campaign before injury cut short the right-back's campaign.
Taft, 19, has underlined his potential with some impressive defensive displays to add to the experience he gained under Noel Blake with England's Under-18 and Under-19 sides.
