بسم الله الرحمن الرحيم
(Fatwa: 1537/1027/L=11/1434)
If the place where his body is lying is free from impurity then he may offer salah in that condition. But if there is impurity beneath his body, then it should be cleaned at the time of salah or some think cloth is spread over there. If there is impurity nearby, it will not affect the salah.
Allah knows Best!
