On 34 minutes, Manchester City loan defender Mills bundled in a close-range shot.

And striker McCammon nodded in Gareth Roberts' 81st-minute free-kick to seal the points.

Now a final-day win at Cheltenham will guarantee promotion.

But Rovers could have had a hatful, if not for a dazzling display from Luton keeper Dean Brill.

His super show began with an early finger-tip save from Mills.

From the following corner, he produced a stunning one-handed stop to turn Mills' header over.

And more heroics were to follow as he denied Gareth Taylor with another one-handed save.
