He withdrew (got ?injured?) because he didn't want to wrestle for the 3rd place. The Russian top wrestlers don't like to wrestle for bronze. During the 2006 worlds I collected quotes from interview in which Russian and US wrestlers talked about the 3rd place. I found them very interesting. Russian and US world team members had completely different attitudes toward bronze.
After losing to Bazri, Pritzlaff said ?Hopefully he carries me through.? After losing to Laliev, Hrovat said ?I hope he goes forward and pulls me back in? and he repeated - ?I hope he goes on and makes the finals.?
On the contrary, after losing to Ganev, Saitiev said he hoped Ganev would lose and wouldn't make the finals. Something similar said also Murtazaliev after losing to Stadnik. I cannot find the original Russian quotes in my PC now but I found the comment of the Russian journalist who reported about the event. She wrote in quasi-religious style: ?The losses of Ganev and Stadnik in the semis deprived Saitiev and Murtazaliev of the consoling opportunity to wrestle for bronze. These losses were actually a boon because they saved the Russian favorite wrestlers from another one moral humiliation.?
