Orient's 3-1 win at the County Ground was marred by a shocking incident midway through the second half, when the supporter ran on to the pitch and attacked the visitors' keeper.
Jones was thankfully unhurt and able to finish the match, and afterwards a shocked Orient manager Russell Slade said: "It was a great win but it was clouded by the fan coming on to the pitch and throwing three punches at my goalkeeper.
"It was totally unbelievable - the worst scene I have seen since I have been a manager.
"Jamie is okay but it doesn't make it right, it is outrageous. He needs a ban for life and should never go to another football match.
"He had a long time in the six-yard box before the stewards did anything."
