Bolton have handed four players one-year contract extensions through to 2017, including defender Rob Holding and striker Kaiyne Woolery.
Holding, 20, made 30 appearances in all competitions this season and was named the club's player of the year.
Woolery, 21, has scored two goals in 19 games this term for the Trotters, who were relegated to League One in April.
Midfielder Tom Walker, 20, and 19-year-old defender Alex Finney have also had their extension options exercised.
Managerless Bolton are bottom of the Championship table, but ended a 14-match winless run by beating play-off-bound Hull City 1-0 on Saturday.
