Real Madrid striker Luka Jovic has been sent back from international duty after sustaining an unspecified injury with Serbia.
The 21-year-old has not had the smoothest of starts to life at Madrid and another injury could add further disruption to the season for the former Eintracht Frankfurt star.
Jovic came off the bench in Saturday's 4-2 home defeat by Portugal, with the Serbian Football Federation confirming the following day that the attacker has sustained an injury, despite being introduced in the 87th minute during proceedings in Belgrade.
