CSKA Moscow striker Aaron Samuel is doubtful for his team&rsquo;s Russian Premier League clash against Terek Grozny this coming Saturday after picking up a knee injury in the 4-1 loss to Zenit St. Petersburg in the Cup final on Monday.<br /><br />The Nigeria international had equalized for the Muscovites in the 36th minute but had to be replaced three minutes later after he landed awkwardly.<br /><br />&ldquo;Tomorrow I will do a scan. I was injured around the 39th minute, I injured my knee after I landed awkwardly,&rdquo;Aaron Samuel told <b>allnigeriasoccer.com</b>.<br /><br />&ldquo;The CSKA Moscow doctor has said that I will have to do a scan to know how long I will be out of action. I can&rsquo;t walk now.&rdquo;<br /><br />CSKA Moscow conceded three goals in the second half and Samuel has revealed that the dismissal of <span class="name">Vasili Berezutski in the 63rd minute contributed to their loss.<br /><br /></span>&ldquo;The game was good in the first half, we were doing well until Zenit scored from a penalty. We mounted pressure, then the equalizer came from me.<br /><br />&ldquo;We lost focus in the second half and got a red card, that is why we lost, &rdquo; Samuel added.<br /><br />CSKA Moscow have won the Russian Cup 12 times since the formation of the club, with their last triumph coming in 2013.<br /><br />Ifeanyi Emmanuel<br /><br />Photo Credit : pfc-cska.com<br />
