Lincoln City and Exeter City have played out a 0-0 draw in Saturday's League Two playoff semi-final first leg at Sincil Bank.
The visitors dominated the opening exchanges but the first effort of the game came courtesy of the hosts on six minutes as Matt Green swivelled and fired into the arms of Christy Pym.
Luke Waterfall then powered a header just over the bar from a 14th-minute corner, while at the other end, Ryan Harley's close-range placed shot was easily caught by Ryan Allsop.
Both sides continued to engage in end-to-end football as Neal Eardley's low free kick from range was kept out by Pym and Jayden Stockley threatened up the field moments later.
The latter stages of the first half then saw Stockley spurn two gilt-edged opportunities for Exeter as the opening 45 minutes eventually finished goalless.
Lincoln came out flying at the start of the second period, Pym deflecting Green's close-range effort wide for a corner and the Grecians having to hold firm at the back.
On 49 minutes, Green forced yet another save from Pym's legs before Elliot Whitehouse's effort on the rebound went over the bar.
Lincoln then hit the woodwork through just before the hour, with Exeter countering through Jake Taylor's close-range effort, which was parried away by Allsop.
For all of the two sides' endeavour to claim a first-leg goal, the game finished goalless and the tie remains on a knife's edge ahead of Thursday's second leg at St James' Park.
