Inches away by Smith! Just wide of the post - a ball was hung into the box by Richards, and the striker glances on a deft header... and it's agonisingly past the upright on the far side!
At the other end, Thorsteinsson catches Akinwunmi in possession - the defender does all he can in the circumstances by forcing the Fulham man a little wide, making it easier for Southwood to cover his angles and push the effort over the bar.
Fossey sends a ball into the Reading area - a first header is won by Warner, into the path of Thorsteinsson, whose header is caught calmly by Southwood.
Close! Barrett whips a cross in from the right; the goalkeeper doesn't know whether to stick or twist. It just evades Smith in the centre, and just out the reach of Davis arriving at the back post...
Another good Reading chance! Frost wins the ball on the right deep inside the Reading half - drives infield, then finds Barrett on the overlap - his strike from a narrow angle is blocked!
A lung-busting run through midfield from Icelander Thorsteinsson is ended just outside the area by compatriot Andresson, who commits a foul in somewhat cynical fashion. Humphrys' free-kick is into the wall.
Not far away from a second goal by Fulham as Adeniran's inswinging delivery escapes everyone and flies marginally beyond the far post.
A great ball from Barrett finds Smith on the run - the striker controls on his chest, tries to lay in Frost, but a tackle comes in just before the midfielder can get his shot away.
Right-back Fossey comes forward for Fulham and sees no better option than punting a shot goalwards - Southwood has it covered.
So close yet again! This time Barrett just pulls a cross-shot past the far post, from the left of goal. It was a neat exchange with East that created the chance. No-one was able to steer in from close-range.
We're into the final quarter of the game and it's still Thorsteinsson's early goal that is the difference.
A dangerous corner from the left by Barrett - hangs it up to the far post, where Andresson attacks the ball, but the goalkeeper is able to collect.
A long throw from Andresson is headed out to the edge of the area, where captain Barrett is arriving... he has a thunderous effort, just over the bar!
GOAL - READING (Tyler Frost 75')
The Royals equalise through Frost - a low cross from Akunwunmi is powered in from 12 yards!
PENALTY - READING
Sam Smith is brought down in the box... it's a Reading penalty!
RED CARD - Taye Ashby-Hammond (Fulham) 77'
The goalkeeper receives his marching orders for the foul!
Barrett misses his spot kick! It's wide of target and the scores remain level!
It's an action-packed game and Reading had the chance to turn the game on its head in the space of five minutes. As it is, the scores are level but Reading have an extra man.
Richards and Davis combine down the left, before Richards just pulls a cross past the far post. So close...
GOAL - READING (Ryan East) 83'
Reading go ahead through Ryan East! His shot from the edge of the area squirms through and into the net!
Minutes remaining and Barrett bursts upfield. Opuku does a good job to recover one-on-one and prevents a goalscoring chance.
YELLOW - Axel Andresson (Reading 88')
A tough tackle on Humphrys leaves the Fulham man in a heap.
It'll be a trip to the winner of Met Police and Wolves in round five... come on #URZ!
