First was funny, Terek's keeper was punching out Zhirkov's cross and hit Dzagoev's head with the ball
Zhirkov was assisting also at second goal, cross from free-kick and Ignashevich put the ball in.
Krasic will be banned for next game (Nalchik away). Rahimic's injury is not so serious as it looked at the first moment, he have not broken arm, only a painful bruise.
Unfortunately I have not watched both that matches, because there was no TV or internet stream transmission.
Match against Saturn can be found at torrents, maybe that against Terek have also been put there
