All the info from team news to tickets and charity collections ahead of the big game...
TEAM NEWS: Russell Slade has the luxury of a near fully-fit squad available with Jamie Jones remaining the only absentee with a back injury.
The U's captain Brian Wilson was substituted at half time in the midweek defeat to Sheffield United with a hamstring injury and has been receiving treatment since then.
Should Brian not make the cut for the trip to Brisbane Road, Joe Dunne may turn to Alie Sesay after his second half appearance against the Blades, whilst David Wright has also played in that position previously.
Alex Gilbey is set to miss out - also with a hamstring injury - whilst Drey Wright and Josh Thompson are currently still out.
Drey has, however been back in training in recent weeks and drawing closer to his first team return.
FORM: Orient are looking for their third victory in E10 on the bounce after returning to the top of the League 1 table last Saturday with a 2-0 win over Swindon Town.
By contrast, the U’s are looking to avoid a third straight defeat and will be hoping to put some further daylight between themselves and the relegation zone. They currently sit three points off of the drop zone but have three games in hand on a lot of the sides around them in the table.
BETTING: Orient are 8/13 favourites, with United at 4/1 and a draw at 11/4. For the full betting with over 50 markets on the match head to www.skybet.com/orient
