Saints loanees Sam Gallagher and Ryan Seager were unable to inspire their respective clubs to victories on Tuesday on a busy night of EFL action.
High-flying Leeds United had too much for Gallagher’s Birmingham City at Elland Road, goals from Samuel Saiz and Stuart Dallas meaning Blues suffered fourth consecutive league defeat.
Gallagher featured for 69 minutes for the visitors and was unfortunate not to open the scoring early on after seeing his low shot blocked from close range.
It was a similar story for fellow forward Seager whose MK Dons side were beaten 2-0 at Peterborough.
The 21-year-old, making his ninth appearance of the campaign, was replaced just before the hour by Osman Sow.
Elsewhere, Harrison Reed was an unused substitute in Norwich City’s goalless stalemate against Burton Albion at Carrow Road.
