Nahki Wells was substituted late in the game as Bristol City suffered one of their most devastating losses of the season last night, Nottingham Forest scoring two stoppage-time goals through substitute Lyle Taylor to win 2-1 at Ashton Gate.

Wells, who came on as a thirteenth-minute substitute in the previous match against Sky Bet Championship leaders Bournemouth because of an early Joe Williams injury, watched from the bench as Forest extended their unbeaten streak to six games with goals in the first and second minutes of added time.

Wells, one of four changes from the Bournemouth game, was replaced in the 83rd minute with City holding on to a slim 1-0 lead given to them by Alex Scott. The 18-year-old midfielder scored in the 39th minute when his shot found the bottom corner from the centre of the penalty area.

Seconds before the opening goal, Wells saw a left-footed shot from outside the box go wide of the right-hand post.

Scott, who was booked in the 66th minute for a bad foul, was substituted in the 77th minute. Minutes earlier, Wells went close with two attempts on goal, the first in the 62nd minute from 35 yards going just over the bar. He then hit a post with another effort from inside the box in the 71st minute after a quick break in which he was set up by an Andreas Weimann pass.

Wells was replaced by Callum O’Dowda in the closing minutes as City tried to hang on for their first home win in the league. However, Taylor, an 81st-minute substitute for Forest, snatched the points for the visiting side with two crucial strikes.

He equalised from the penalty spot after Nathan Baker conceded a foul. The winner came a minute later when Taylor scored from close range into the bottom right-hand corner to stun City and their fans.

Instead of climbing from eleventh to eighth with the win, City dropped to thirteenth in the Championship with their fifth loss of the season.

City face another tough match on Saturday when they travel to the West Midlands to meet second-placed West Bromwich Albion.

• Jonte Smith and his Ballymena United team suffered a 4-0 home loss to Larne in the quarter-finals of the County Antrim Shield last night. The visiting side scored two goals in each half to seal the win.
