Ross County completed a double signing ahead of Saturday's Scottish Cup fourth-round victory over Dundee United in Dingwall.
Midfielder Oscar Gobern (pictured) has moved to the Global Energy Stadium on a deal until the end of the season after leaving Mansfield. The 25-year-old can count Southampton and Huddersfield among his former clubs.
Also joining the Staggies is winger Milan Lalkovic. The 24-year-old from Slovakia has agreed a loan switch from Portsmouth - he was with Chelsea as a youngster and has also turned out for Barnsley and Walsall.
