Nottingham Forest's Championship match against Burnley remains goalless at half time.
Forest started on the front foot, but were limited to long-range efforts in the opening 10 minutes.
First, Henri Lansbury took aim from 35 yards before David Vaughan directed the ball wide from a similar distance two minutes later.
Nelson Oliveira, looking to add his second goal in Forest colours, tested Tom Heaton in the 17th minute but the 29-year-old saved comfortably.
The England goalkeeper was called into action again when Lansbury's 20-yard effort was powered towards the bottom right corner.
Sam Vokes twice came close to scoring before half time, but could not direct a pair of headers on target.
