Operation shore-up? Defender Jordan McGhee is on for Jamie Walker. The Hearts winger has put in a real shift and served up a wonderful cross for Juanma's second goal.
Ash Taylor, who has gone down with cramp a couple of times, lumbers off to be replaced by Andrew Considine. Aberdeen have used all of their subs now. Is this game slipping away from them?
Aberdeen right-back Shay Logan is the latest player to be booked for a spot of retribution on Hearts' goalscorer Juanma.
Hearts make a change in central midfield for the final 10 minutes as Prince Buaben is replaced by Miguel Pallardo.
The bookings are as regular as the number 21 bus to Tynecastle as Juanma goes into Steven McLean's book for clattering into Kenny McLean.
Aberdeen midfielder Craig Storie makes way for Cammy Smith, while Ash Taylor appears to be struggling with cramp but it will take more than that to force the big Dons defender off.

"Scotland have enjoyed a few walk-overs in this group, but despite the healthy look on the scoreboard they are not getting everything their own way. Slovenia's Kaja Erzen twice in a matter of minutes sizes up the goal but her finishing is disappointing.
"Scotland could do with another goal to make this comfortable."
Willo Flood bustles his way forward and lays off a nice cross for Niall McGinn to run on to but the Aberdeen forward can't steer his effort on target from 10 yards or so. He should really be doing better there...
Another shot straight at the Aberdeen keeper as Jamie Walker cuts in from the right wing and lets rip with a fizzer.
Hearts are well on top now as Sam Nicholson's shot is blocked and the ball rolls out to Arnaud Djoum who can only fire straight at Scott Brown.
Juanma is proving a real handful for the Aberdeen defence as he threads a pass through to Jamie Walker, who turns and fires a shot wide. Prince Buaben was wide open in front of goal and screaming for a pass...

"Clinical header from Juanma but also an incredible ball in from Walker. The noise inside this old stadium is immense. Long way to go though and I suspect we haven't seen the net bulge for the last time this evening."
It's a second goal for Juanma as Jamie Walker does brilliantly to reach a long ball over the top to whip across a lovely cross and the Spanish striker can't miss with a header from a couple of yards.
Another booking as Jonny Hayes is upended by Igor Rossi.
Shay Logan does well to make room for a cross from the right and it lands perfectly for Niall McGinn at the back post. However, the Dons forward lacks conviction and a weak header slips wide from a very promising position.

"No sign of the either side dropping the tempo in this match. You can't take your eyes off it and referee Steven McLean is being forced to make some big calls as both sides fight frantically for the lead."
A lovely turn from Igor Rossi - he is Brazilian after all. Then the Hearts defender cracks a shot from 20 yards against the post, with Scott Brown clutching at fresh air.
Great chance for Hearts! Juanma gets the better of a clumsy Ash Taylor and drives the ball across goal. Shay Logan should deal with it but slips and the ball squrims under him in the six yard box. Here comes Prince Buaben but he can only sky it over, via a slight deflection. Hearts are claiming the ball brushed the arm of Logan there...
A draw is not much use to either side, so expect more thrills and spills at Tynecastle. It's all a bit untidy at the moment as John Souttar leaves the park for a blood injury, with Hearts defending a corner...
