What happened: The 22-year-old joined Portland in January 2025 for just under $6 million. He is set to travel to Glasgow after his visa is cleared, with a medical and final formalities still ahead.
Why it matters: Kelsy leaves as Portland's leading scorer this season while the club sits ninth in the Western Conference. The fee trails only Tore Andre Flo's 2000 move in Rangers history.
By the numbers: Kelsy scored 16 goals in 43 MLS appearances for Portland. The guaranteed fee is at least $7 million above Portland's initial outlay before add-ons and any future sell-on return.
What to watch: Visa clearance and the medical are the remaining steps before the transfer can be finalized.
