United had trailed to Dan Turner's 19th minute opener at the Jakemans Community Stadium, but secured a share of the spoils when Shiels headed home Joe Leesley's 51st minute corner.

A double save from the Brakes' Callum Hawkins kept out Danny Elliott and Scott Pollock - as the Pilgrims were frustrated in their attempts to seal a second successive home victory.

Leamington squandered two early chances through Turner, forcing Marcus Dewhurst into a smart save, and Kelsey Mooney - but the Brakes edged ahead when TURNER crashed a loose ball home from close-range.

United's first meaningful effort on goal drew them level six minutes after the break - with SHIELS powering home Leesley's inviting corner delivery.

Leamington's on-loan goalkeeper Callum Hawkins made a fine double save to deny Elliott and then Pollock - but chances remained at a premium at both ends.

Dewhurst did make a routine stop to palm aside Stephan Morley's late free-kick, as honours ended even in a contest that will not live long in the memory banks.
