Substitutes Folarin Balogun and Nathan Tormey scored as Arsenal came from two goals down to draw 2-2 with Swansea City, whose hopes of avoiding relegation were dented.
Swansea scored two quick goals in first-half stoppage time at Meadow Park, through Liam Cullen then Matthew Blake, with a 20-yard free-kick.
Arsenal ramped up the pressure in the second half. Balogun had a shot cleared off the line before scoring on 83 minutes.
Three minutes later Tormey finished from a tight angle to level the scores.
Swansea's Joe Lewis received a second yellow card but Arsenal could not take further advantage.
They stay seventh, level on 24 points with Manchester City, but with a match in hand.
Swansea remain bottom on 15 points.
