The Sun reports that - in scenes to be broadcast next month - the pair end up trapped in Max's car after he hits a lorry on the way to his ex-wife Tanya's wedding.
News that Max would suffer an accident on Tanya's happy day first emerged last month, but exact details of the stunt in store had been unknown until now.
It is thought that Max and Abi both suffer injuries in the crash and require a trip to hospital. Tanya is then expected to hear the news shortly after she exchanges her vows with fiancé Greg Jessop - prompting her to flee from the church.
The accident has also been tipped to spark the conclusion to the soap's current baby swap storyline. Yesterday, it was reported that Ronnie Branning comes to her senses while visiting Max following the incident, as she gave birth to her late son James at the hospital where her brother-in-law receives treatment.
While at the hospital, Ronnie reportedly realises the enormity of her decision to steal Kat Moon's baby and later makes a dramatic confession, leading to Kat being reunited with her son.
