The mechanic quickly suspects who might be responsible for the incident

MACKENZIE Boyd is set to be fighting for his life after shock injuries in upcoming Emmerdale scenes.

The mechanic – played by Lawrence Robb – finds himself blocked in a barn by a bull.

Determined, he psyches himself up to dodge the bull and make his way to the barn gate.

Mack makes a desperate run for it while the bull chases him.

Later on, Nate (Jurell Carter) hears a groan as he rushes to help an injured Mack.

In recent weeks, Mack has formed a rivalry with newcomer John Sugden (Oliver Farnworth).

Alongside Aaron Dingle (Danny Miller), the pair stole John’s van – also his home – and left it by a lake.

Unfortunately, the handbrake off so the van rolled in as a result.

Mack is convinced John is responsible for putting the bull with him in the barn as revenge.

In scenes yet to air, Aaron confronts John – with the pair having had their own tensions – but passion soon takes over.

Charity (Emma Atkins) tries to motivate Mack for an afternoon planning revenge on John.

However, he goes quiet and woozy before collapsing on the sofa.

This leaves Charity horrified that something serious has happened.

What will happen next with Mack?

The latest update follows viewers demanding that Mack and Aaron be axed after destroying John’s home.

John is the newly-discovered half-brother to Victoria Sugden (Isabel Hudgins), who’d been living a nomadic lifestyle in his van.
