Bali Mumba enjoyed a memorable loan debut for Peterborough United as he came off the bench to score an FA Cup winner with a brilliant individual effort.

The 20-year-old joined Posh from Norwich City in midweek and came off the bench at half-time at left-back with the hosts being held at 1-1 by League Two visitors Bristol Rovers.

Mumba changed that in the 63rd minute with an interception in the opposition half, exchanging a one-two with a forward and squeezing past two men to cut onto his right foot and stroke the ball low into the bottom-right corner.

Another City loanee, Danel Sinani, was involved as Huddersfield took a Premier League scalp. Burnley were leading 1-0 when the forward was taken off by the visitors just before the hour mark but the Championship side scored two late goals.

Onel Hernandez came off the bench in the 62nd minute to help Middlesbrough avoid an upset with a 3-2 win away to League Two side Mansfield, applying the pressure in the box in injury-time as an own goal settled the tie.

Elsewhere in the third round, there were upsets involving former City academy players.

Hartlepool United earned a Championship scalp with a 2-1 home win over Blackpool, with goalkeeper Ben Killip and defender Timi Odusina playing the full match. Former City left-back James Husband was forced off injured in the first half for Blackpool.

Left-back Caleb Richards started for the lowest-ranked team still in the competition, Kidderminster Harriers, and set up the equaliser as he headed down a cross during a memorable 2-1 home win over Championship side Reading.

Richards spoke to Pink Un+ about his career so far ahead of the game, highlighting an increase in assists this season.

Canaries legend Wes Hoolahan, at 39 years old, came off the bench in the 61st minute to help Cambridge secure the upset of the day as they clung on to a 1-0 triumph over Newcastle United at St James' Park.

There were former Norwich players on the score-sheet around the country in the third round, including James Maddison as holders Leicester won 4-1 at home against Watford.

Carlton Morris came off the bench to put Barnsley 4-3 up at home to Barrow, only for the League Two team to find another equaliser in a chaotic game at Oakwell, forcing extra-time.

Morris then scored his fourth goal in four games as he settled the tie 12 minutes into the first half of extra-time, to earn a 5-4 win.

Dani Ayala headed in a late equaliser for Blackburn at Wigan but the Championship visitors conceded in injury-time to lose 3-2 away to League One opposition.

Away from the cup action, Tom Dickson-Peters endured a difficult debut for Gillingham in League One, with the hosts already 3-0 down to Ipswich when he came on at half-time.

Town added a fourth and the Gills had a man sent off in the second half.

It was a happier debut for fellow striker Tyrese Omotoye in League Two though, playing 75 minutes of Carlisle's 2-0 home win over Bradford to continue pushing away from the relegation zone.

In the National League, Matthew Dennis' renaissance continued with a third goal in three games for Southend, scoring the only goal in the fifth minute, away to survival rivals Weymouth.

Another City loanee was on target in Scotland, with midfielder Reece McAlear scoring an equaliser in the 86th minute as Inverness earned a 1-1 home draw with Championship promotion rivals Raith Rovers.

The youngster had come on at half-time and found the net with a low effort from 25 yards.

Meanwhile, Aston Oxborough was kept busy as Barnet were held to a 1-1 draw at home by National League mid-table rivals Altrincham.

The goalkeeper also spoke to Pink Un+ this week, discussing his recovery from 18 months out due to a serious injury.
