David Raya was Southport's hero as they pushed Derby County all the way in the third round of the FA Cup.
Playing his last game of a successful loan spell with the Sandgrounders, the young Spaniard made a string of fine saves in a man-of-the-match performance at Derby's iPRO Stadium.
However Southport's hopes of a lucrative replay at Haig Avenue were dashed in injury-time when the home side were awarded a 93rd minute penalty.
Although Raya dived the right way, he was unable to prevent Rams top scorer Chris Martin, on as a second half substitute for Leon Best, from deciding the tie in Derby's favour by the closest of margins.
Elsewhere in loan action this weekend, Josh Morris ended his six-month spell with Fleetwood with two goals but it wasn't enough as they drew 2-2 at home to Swindon Town.
Morris opened the scoring for the home side with a fine near-post finish four minutes into the second half, and ten minutes later took his goal tally during his stay at Fleetwood to four with another composed strike.
But with a chance to leapfrog rivals Bristol City at the top of League One, Swindon fought back to claim a point. Andy Williams reduced the deficit on 71 minutes, before the Robins secured a share of the spoils two minutes from time through Louis Thompson.
Burton Albion continued their fine form under manager Jimmy Floyd Hasselbaink with an important victory in the chase for promotion from League Two.
Darragh Lenihan played the full match in midfield as the Brewers defeated rivals Shrewsbury Town 1-0 at the Pirelli Stadium, thanks to George Taft's goal on the hour.
The win sees Burton go above the Shrews and into second place in the division.
Lenihan's loan deal was due to expire after Saturday's match but impressive displays for the Brewers has seen it extended for a further month.
