Andy Fisher was the Northampton hero last night, as the League Two side defeated Arsenal on penalties in their opening group game of the Leasing.com Trophy.
The highly-rated Rovers goalkeeper joined the Cobblers on loan last week and made his debut in the cup clash against the Gunners on Tuesday night.
Fisher made smart saves to deny Nathan Tormey and Trae Coyle, as the tie finished 1-1 at the end of normal time thanks to goals from Arsenal's James Olayinka and Northampton's Sam Hoskins.
The 21-year-old then denied Coyle again in the shoot-out, as Keith Curle's side won 4-3 on penalties to secure the extra bonus point.
Rovers boss Tony Mowbray hopes the loan spell at Sixfields will be the making of Fisher, who is tipped for a bright future at Ewood Park.
"The main thing for me is that (Andy) Fisher has to go and try and play some football somewhere," said the manager.
"He needs to grow up, become more mature, have big centre-halves screaming at him for not coming for crosses and fans moaning at him if he lets a soft goal in.
"I think it's time to see whether he can be a goalie for Blackburn Rovers and rather than keeping him around as a number three, playing the odd Under-23s game, I think it's more important that he goes out and sees whether he's going to be a goalie or not."
Scott Wharton, who is also on loan at Northampton, missed the match through injury, while fellow Rovers defender Tyler Magloire played the full 90 minutes as Rochdale defeated Carlisle United 2-1 in the second round of the Carabao Cup. They will now face Manchester United at Old Trafford in the third round.
