Dundee United can confirm Declan Glass agreed a new contract extension - ahead of a short-term loan move to Derry City.
Academy graduate Glass, 22, has agreed a new one-year extension that will take his existing contract until 2024.
The attacking midfielder will also join SSE Airtricity League side Derry on loan until November as part of his development.
He will join former United team-mate Mark Connolly at the title-chasing Irish side, after Mark completed a permanent switch to Derry earlier this week.
Declan enjoyed a similar loan spell last season where he helped Kilmarnock secure the cinch Championship title.
Sporting Director Tony Asghar stated "Declan moving to Derry City on loan allows him the opportunity to continue his development in a first team environment.
"Last season, in coming back from a serious injury he had a stop-start season but we have all see the qualities has has in his time playing for United.
"We need to give players an opportunity to play games regularly to be a long-term asset for Dundee United.
"By extending his contract, we are committing Declan to rise to that challenge.”
