That source requested anonymity because they were not authorized to speak publicly on the agreement. The deal, worth some $13m/£9.5m – potentially more if Kelsy hits certain performance goals for Rangers – also includes a sell-on fee for the MLS club.

The Athletic’s Tom Bogert first reported details of the deal on Wednesday morning.

Portland acquired Kelsy from Ukrainian side Shakhtar Donetsk last January, paying $6m for the Venezuela international. The 22-year-old has been erratic but ultimately productive for the Timbers, finding the back of the net 16 times in 43 appearances.

Portland had little intention of moving Kelsy this window, a source said this week, but the fee, a club record for an outgoing transfer, proved impossible to turn down. The Timbers already added a center forward this summer – former Tottenham and Monterrey striker Vincent Janssen – and might make other moves before the window closes.

Portland currently sit at ninth in MLS’ Western Conference, only narrowly in position for the final play-in spot to the MLS playoffs. They have already navigated a coaching change earlier in the season, with nPhil Neville dismissed during the World Cup break. Former Leicester City and QPR boss Martí Cifuentes took over in July.

Rangers sit ninth in the Scottish Premiership after a tumultuous opening to their season which has seen them yet to win in the opening two games of league play and drop the the Uefa Europa Conference league after losing a Europa League qualifying tie to Polish side Jagiellonia Białystok. An anemic attack has seen McInnes push the club to sign reinforcements, having already added former Girona winger Kim Min-su and Japanese winger Daisuke Yokota earlier in the summer.

Kelsy will travel to Glasgow this week to finalize the deal and undergo a medical and will join the team permanently when his visa is sorted. A source said on Wednesday that Kelsy is highly unlikely to feature for Rangers this weekend, when the club takes on eighth-place Aberdeen on Sunday.
