Manchester United conceded a late equaliser to Bolton Wanderers and were beaten 5-4 in a penalty shoot-out in the Lancashire Senior Cup quarter-final.
Warren Joyce's holders lost the grip on the trophy despite leading for much of the game through a Joe Rothwell spot-kick as Zach Clough popped up with a late equaliser for the dogged Trotters.
Tom Thorpe returned as captain after an ankle injury cut short his loan at Birmingham City and his goal-saving challenge on Andy Kellett proved his fitness. Tame efforts were then provided by Clough, Rob Hall and United's Andreas Pereira before a dramatic spell unfolded.

However, Kelly's 85th-minute shot dipped over Joel Castro Pereira's bar and, soon afterwards, a free-kick from the right was touched in by an unmarked
