Championship side Charlton Athletic were held to a 0-0 draw by League One outfit Peterborough United at London Road this evening.
Peterborough's Ben Alnwick made several smart saves to keep his side in the tie, the first of which came when the former Tottenham Hotspur goalkeeper dealt with Johann Gundmundsson's powerful long-range strike after just six minutes.
Stephen Henderson in the Charlton Athletic goal got his first taste of the action when he kept out Nick Ajose's swerving effort midway through the first half.
Alnwick was again called into action just before the break when he had to react quickly to keep out another powerful effort from Gundmundsson.
The best chance of the second half fell to Kyle Vassell on the hour mark, but after controlling a long ball forward, he could only send his shot wide of the far post.
