Norwich City and Ipswich Town are goalless at the break in their Championship playoff semi-final second leg.
The first chance at Carrow Road fell to the visitors when Daryl Murphy headed over following Kevin Bru's cross.
Russell Martin struck a low shot towards the bottom corner of the Ipswich goal, but Paul Anderson was on hand to clear off the line.
It was a nervy opening 45 minutes in the East Anglian derby and few telling chances were created as the half passed by.
With under five minutes left of the first half, Jonny Howson's shot was blocked by Tyrone Mings.
