Slavia Prague have suffered a huge injury scare ahead of tonight's Europa League quarter-final showdown with Arsenal after goalkeeper Ondrej Kolar appeared to suffer a serious injury in training.
Kolar, who only recently returned to fitness from a fractured skull sustained in last month's match against Rangers, picked up an injury to his shoulder while trying to save a shot from Nicolae Stanciu in training on Wednesday night.
Romanian star Stanciu consoled the 26-year-old before he received medical attention from a physio and left the session.
Kolar appeared to be in real pain and was struggling to lift his arm up, sparking concerns he'll have to miss this evening's quarter-final second leg in the Czech capital.
Arsenal travel to Prague with the scores finely poised at 1-1 after Tomas Holes scored a last-gasp equaliser at the Emirates last week.
However, Kolar's injury will come as a huge blow to Prague and marks the latest setback in a difficult month for the keeper.
The Czech international sustained a horrific facial injuries and a fractured skull at Ibrox last month after Kemar Roofe's boot connected with his head during a challenge for the ball.
The Rangers striker was subsequently sent off and also given a four-game ban while Kolar will now have to wear a protective helmet for the rest of his career.
Speaking about the incident for the first time this week, Kolar revealed Roofe has not apologised to him and claimed he could have 'ruined someone's life'.
'I read what he said. He said he was first to the ball, but he didn't add that he kicked it out of my hand, collided with my leg and hit me on the head,' Kolar said.
'He saw me the whole time. Anyone who has ever kicked a ball knows that the foot can always be pulled down. It's a game of football, it shouldn't be about my health.
'If I ever met him again I'd say nothing. I'd wait for him to see if he apologised and asked about my health.
'I waited for Roofe to write me a message on Instagram for example. Instead, I read hate messages from Rangers fans, 'he should have kicked your head in'...'he should have broken your spine.'
'I know things aren't good between Slavia and Rangers right now, but that?
'I was disappointed that Roofe did not apologise through the media. I'm not vindictive, I don't need him to give me something back, but he should think more because maybe the next time, he could ruin someone's life.'
