Norwich City Under-21s missed the chance to pick up three valuable points in Premier League 2, as an injury time goal for Middlesbrough would leave them with just a point apiece.
Alan Neilson's men headed in at the break in front thanks to a goal late in the half from the returning Jon Rowe.
Rowe, who has been out for the majority of this season, got on the end of a crisp Sam McCallum cross to divert the ball home from close range.
And the young Canaries looked to be more comfortable in the second half too with Ben Watt dictating play in front of the back four.
However, a goal from substitute Isiah Cornet in the 84th-minute would level matter before a frantic finish.
Within a minute of conceding, Harry Brooke's work to force Boro into trouble ended with Luke Woolston slamming the ball into his own net.
This sparked a response from the visitors and they manufactured numerous chances in the closing stages, most of which were dealt with comfortably by Jon McCracken.
That was until George Gitau headed home in the third minute of stoppage time to rescue a point for Middlesbrough.
