Andrei Markov was forced to leave a KHL game Friday after suffering an "unknown injury" in the second period and didn't return. This from Pavel Lysenkov of Sovietsky Sport. Markov hasn't exactly been the most durable player during the past few seasons of his career. He played a combined 20 games the last two seasons because of knee woes and participated in just 45 in 2009-10. He has one point in nine games for Vityaz Chekov.
