Bolton Wanderers have failed to turn their chances into goals after 45 minutes of a hard-fought Championship clash with Huddersfield Town.
The home side were in control from the outset as David N'Gog dragged his shot wide from a tight angle.
Huddersfield were forced into a change after 15 minutes when Jack Hunt went down injured, with Callum Woods coming on to take his place in midfield.
Woods was quickly involved as his powerful strike from distance went just inches wide of the far post.
N'Gog then spurned a glorious opportunity when he scuffed wide from six yards following a fine approach-play from Chris Eagles.
Sean Scannell and James Vaughan both looked lively on the break for the visitors but both sides were forced to settle for a frustrating stalemate at the interval.
