Southend keeper did not break ankle
The 30-year-old managed to finish the game against the Bulls, before having an X-ray on his right ankle.
"X-rays have shown that there isn't a fracture which is better than first thought," he said.
"The doctor thinks I have severely sprained my ankle and I am going to have an MRI scan on Monday.
"It doesn't look good though as my ankle has ballooned up and I have been on crutches since the end of the match.
"I was in a lot of pain but decided to play on. I just didn't want to come off and let the team down because we really needed the win.
"There wasn't a substitute goalkeeper to come on and I felt that I could run it off, although the doctor and physio were advising against it."
