Both sides had to settle for a point apiece from this Wessex League Premier Division encounter.
But it was anything but a bore draw as both teams had plenty of half chances to break the deadlock but neither had their shooting boots on for the key situations.
The home side had the first chance of the game when Joel Jackson picked up the ball on the left and cut inside before hitting a shot which was always going away from goal.
At the other end Tadley attacked down the left and Josh Warren only cleared the cross into the box as far as Samuel Hamilton on the edge of the box but he drilled his first time shot wide.
The home side thought they should have had a penalty on 15 minutes when Jack Breed was fed in down the left side of the box and he dinked the ball past Sean O’Brien before being cleared out by the keeper’s challenge but nothing was given.
Two minutes later Matt Simm found some space on the right and crossed the ball to Mike Turvey but he put his header straight at O'Brien.
Portchester went close again on 28 minutes when the ball was worked forward down the right before being worked inside to Jackson.
From 15 yards out he tried to chip the keeper but his effort went over the target.
A defensive slip almost let in the visitors when Daniel Vickers took the ball off keeper Charlie Searle and tried to hit his shot first time into the open net but it ended up going well wide.
Tadley then broke down the right before the ball was played inside to Connor Thorne who tried his luck from 25 yards out but his shot hit the crossbar.
Portchester had the first chance of the second half when a ball from the right found Marco Giambelardini just inside the penalty area but his shot went straight at O’Brien at his near post.
Tadley went close again on 56 minutes when they broke forward through the middle and the ball was slipped into the path of Vickers inside the box. However, just as he prepared to unleash his shot a defender got back in time to block the danger.
The visitors had a similar chance ten minutes later when the ball was crossed into the box from the left and found Brett Denham. But just as the striker was about to shoot Ben Buckland timed his tackle perfectly to clear the ball off his foot.
The home side had another opportunity on 73 minutes when substitute Stuart McConnachie worked the ball inside to Jack Breed and O’Brien was rooted to the spot but the shot whistled just wide of the post.
Denham had another chance to break the deadlock at the other end following a break down the left but when he received the ball inside the box he fired his shot straight at Charlie Searle.
With five minutes remaining Portchester lost the services of Hardy who received his second yellow card in a matter of minutes - a decision most of the home contingent felt was especially harsh from the referee.
In injury time Tadley almost snatched the three points when Thorne got clear of Buckland on the right and crossed the ball into the feet of Denham but just as he shaped to shoot, Adam Cripps got back to block the ball and the danger was cleared.
