Leyton Orient boss Martin Ling feels his side's 2-0 win at Bradford has all but secured their League One status.
"We're not quite safe yet, but we're nearly there," said Ling, whose side are five points clear of the League One drop zone.
"We won't be comfortable until we are mathematically safe, but it is very difficult for the teams below us to catch us now.
"A win against Nottingham Forest would put all the demons to bed."
