THE O'S will learn their potential third round fate before Sunday's game at Alfreton Town kicks off but assistant manager Kevin Nugent says that won't affect his players.
The third round draw is due to take place at 2.40pm with the O's not kicking off until 3.15pm.
Nugent insists nothing will shift Orient's focus from the job in hand at the Impact Arena - not even a dream draw against one of the Premier League big boys.
He said: "The draw's going to be about 35 minutes before we kick off. We won't have it on in the dressing room or anything like that, but I'm sure the players will hear the draw from supporters during the warm up.
"But that'll be irrelevant if we don't get through so the focus will purely be on the 90 minutes that's going to be ahead of them.
"It's a massive game for the club in terms of monies, in terms of television and it's going to be a very tough game.
"It will be a similar kind of test to the last round. They play some decent football, they're quite a strong side and we've done the same research on them and given them the same respect we would give any other team.
"They're only a couple of leagues below us so there certainly won't be any underestimating of them at all. We're treating it as if it's going to be a very tough game."
