Ross County have signed Aberdeen forward David Goodwillie on loan, while the Dons have added Welsh international striker Simon Church on a similar deal.
Staggies manager Jim McIntyre was looking to add to his attacking options following recent injuries to Liam Boyce and Craig Curran and has agreed a deal to take Goodwillie until the end of the season.
The former Dundee United man has featured in 25 Dons games this season but has scored just twice, with both goals coming in the same game, against Hearts in September.
The Dons have moved quickly to replace Goodwillie, signing Welsh international Church on loan from MK Dons.
The 27-year-old played over 100 games for Reading before spending two years at Charlton and then joined Milton Keynes Dons last summer.
Church has scored three goals in 23 appearances for MK Dons this season and has 33 caps for his country.
