The 26-year-old played over 200 times for Orient before joining the Saddlers on a free transfer last summer.
Orient are looking to register a fourth consecutive win at Brisbane Road and Ibehre is looking forward to renewing old acquaintances.
"I'm really looking forward to the game, but I will be a little nervous about the reception I'll get," Ibehre told the Ilford Recorder.
"I know Orient need the points, so I just hope that Saturday's game will be a fair result.
"A lot of my family and friends will be at the game, and it will be great to catch up with the Orient boys afterwards."
