Rangers finalize deal for Portland Timbers striker Kevin Kelsy

• $13m fee is an outgoing record for Portland

• Kelsy not expected to feature this weekend

Rangers have acquired forward Kevin Kelsy from Major League Soccer's Portland Timbers, a source with direct knowledge of the deal told the Guardian on Wednesday. That source requested anonymity because they were not authorized to speak publicly on the agreement. The deal, worth $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, scoring 16 times in 43 appearances.
