Cheltenham manager Mark Yates saw his side slip to fifth in the table after being held to a goalless draw by play-off rivals Bradford - but admitted that he was far from disappointed.
The Robins will now play Northampton Town over two-legs with the Bantams facing Burton Albion with a place in the Wembley play-off final at stake.
"Bradford are a really, really good side - they got to the final of the Carling Cup - so I'm not too disappointed that we won't be playing them," Yates said. "That's no disrespect to Northampton who are also a good team with a top manager but Bradford are a really good team.
"We are in the play-offs and that's a great achievement for the players on the back of the disappointment of last year. We have to use that in a positive manner to make sure that we are as good as we can be on Thursday and as good as we can be on the following Sunday.
"The league doesn't lie after 46 games and we are right up there with the best. We can be a little bit disappointed because we have not got that third spot but we need to go back to work and get ready to go again."
Cheltenham has the pick of the chances throughout with Bradford finishing the game with 10 men after defender Andrew Davies picked up two yellow cards. But their best efforts came late on when Pack crashed his header against the upright and substitute Shaun Harrad forced a good low save from visiting keeper Matt Duke.
The Bantams will be without Davies for the first leg of their play-off semi-final and that was frustrating for assistant manager Steve Parkin who thought the defender's first booking - for a challenge on Byron Harrison - was harsh.
"Andy D'Urso is a very experienced referee and he was stood very close to the incident," Parkin said.
"Not for one minute did he look as though he was going to give a foul but he has then got involved with his own linesman who was further away. We were disappointed with that.
"Andrew was then told in no uncertain terms at half-time that he had to be whiter than white and not to get involved in anything but he has then had a silly sending off which means he will miss one of the games next week which has put a slight cloud over the day."
