5. Stephen McLaughlin - 5
His brilliant run and cross set up the Stags opener, but found it tough going defensively. Comfortably beaten by Morris out wide for Luton’s equaliser and had his blushes spared twice by Liam Roberts after two errors just before half-time. Photo: Chris & Jeanette Holloway
6. Dom Dwyer - 5
First appearance since New Year's Day after replacing McLaughlin on 79 minutes. Useful fresh pair of legs to give Mansfield an important attacking presence but didn't help further his cauase for more game time. Photo: Chris Holloway
7. Louis Reed - 7
Protected the defence well and got in some important tackles to stop Luton in their tracks. Forced off after picking up a knock just before the hour mark Photo: Chris & Jeanette Holloway
8. Nathan Moriah-Welsh - 5
Replaced Reed on 58 mins, but failed to really impact the game and help Stags win back a foothold in midfield. Chasing Palmer’s shadow at times. Photo: UGC
