Ally Gilchrist is defending the near post again but this time he deals with Harry Forrester's low delivery properly, knocking it away for a corner.

Rangers are ahead and in control.

Poor Ally Gilchrist knocked in an own goal... Painful for the big man.

Barrie McKay finds room on the left and whips in a dangerous cross. All it needs is a touch but Rangers skipper Lee Wallace is inches away from connecting in front of goal.

Scott Ross moves into central defence for Peterhead with substitute Jamie Stevenson, once of Real Mallorca, slotting in at right-back.

Those bandages haven't saved the day for Ryan Strachan and he has to trudge off, with Jamie Stevenson his early replacement.

Peterhead are down to 10 at the moment as central defender Ryan Strachan gets some strapping taped round his leg behind Graeme Smith's goal.

Peterhead's Graeme Smith needs to make a smart, low stop to keep out a glancing header from Kenny Miller from a deep Andy Halliday cross. 

Rangers are building up a bit of steam here as Andy Halliday swaggers past a couple of challenges then thunders in a shot, which is headed over by a defender in white.

Kenny Miller surges into the penalty box for Rangers and lays it off for Harry Forrester, who takes aim for the far top corner but a deflection takes the ball high over the crossbar.

It's all a bit Keystone Cops, with players slipping and sliding on the shoddy Hampden surface. In between the pratfalls, Peterhead have had a few nice touches.

Rangers are knocking a few long balls over the top but there's not much room to work with behind the Peterhead defence.

Peterhead don't look overawed by the occasion, with the part-timers knocking the ball around when it comes their way and sitting quite deep in their own half.

A few bobbles on the pitch already making life difficult for the teams. Pass-backs to the goalie could be interesting...

Jason Holt drives at the heart of the Peterhead defence after a mistake from Ryan Strachan but he just over-runs the ball, allowing Scott Ross to get a toe in. 

Referee George Salmond peeps his whistle and we're off at a packed Hampden. 

There are around 2,500 fans down from Peterhead and they are making quite a racket even though they are heavily outnumbered.

Forget Rory Mc at the Masters, Peterhead's Rory McAllister could be the star of the weekend. The 28-year-old striker has an impressive haul of 31 goals from 38 games this season, including five against Falkirk in the second round of this competition.

A plumber by trade, McAllister has been prolific throughout his lower league career.

Peterhead may be underdogs today but they can take heart from recent success against Rangers.

Back in August 2012, Rangers began life in Division Three with a very uncomfortable 2-2 draw at Balmoor, with the visitors needing a last-minute goal. Later in that campaign, Peterhead enjoyed a shock 2-1 victory at Ibrox.

The teams have met already this season, with Rangers easing to a 3-0 win at Ibrox in the League Cup.    

The trophy cabinet at Peterhead's Balmoor is packed full of Highland League silverware and many Aberdeenshire Cups but their only senior success to date is the League Two title in 2014.

To be fair, the Blue Toon have only been in the senior set-up since 2000 and this season they are ticking along nicely with a chance of promotion to the Championship via the play-offs.
