Dynamo Kiev loanee Ayila Yussuf&nbsp; will have to spend five months on the sidelines after picking up an injury while in action in the Europa League on Thursday evening.<br /><br />In the 76th minute of the encounter between Metalist and Legia Warsaw, the experienced defender had to be replaced after feeling pains.<br /><br />Initial evaluation by club medics suggests that the Nigeria international can only resume full practice in March, assuming he does not suffer a relapse during rehabilitation.<br /><br />Therefore, the 29 - year - old will sit out the three remaining matches in Group L of the Europa League, meaning he will only feature in the competition again this season if Metalist qualify for the knock out rounds.<br /><br />At this stage, that is looking very unlikely as the Ukrainian bronze champions have lost their opening three games, and are 6 points behind second on the table Trabzonspor.<br /><br />Ayila Yussuf is tied to Metalist until the end of the&nbsp; 2014 -&nbsp; 2015 season.<br /><br /><br />Photo Credit : fcdynamo.kiev.ua.<br />
