Blackburn has completed the signing of Partizan Belgrade midfielder Radosav Petrovic for an undisclosed fee.
Petrovic, 22, has signed a four-year contract with Blackburn after having received a work permit. The 6ft 4in defensive midfielder has made 19 appearances for Serbia, having made his debut for the country in August 2009.
Petrovic started his career at hometown club FK Jedinstvo Ub. A move to Radnicki Obrenovac followed, before he moved to Partizan in the summer of 2008.
He was named in the Serbian league team of the year for the last two seasons and is currently with his international colleagues ahead of Serbia's international match against Russia in Moscow.
Blackburn face a race against time to make sure Petrovic is eligible for Saturday's Premier League opener against Wolves at home.
He is the club's second signing this summer, following Dundee United striker David Goodwillie to Ewood Park.
