Dinnington missed the opportunity to move up to third in the North East One after a late try forced them to share the spoils at Wheatley Hills on Saturday.
The 20-20 draw meant Dinnington slipped to fifth in the table.
As always, when these two sides meet, this was a very competitive game.
Wheatley had a chance to take the lead in the opening minute but were off target with a penalty kick from the 10 metre line.
Dinnington came back winning a penalty for tripping which they kicked to the corner.
A collapsed maul gave them another chance and from the following lineout they set up a rolling maul to put Jalan Farris over.
Jonny West added the conversion.
innington kept the pressure on and with only 10 minutes played, Wheatley had a player binned for not rolling away.
Just before the mid-point of the half, West kicked Dinnington further ahead with a penalty but two minutes later Wheatley replied in kind.
There was then not much between the two sides until five minutes from half-time when Dinnington had a player binned.
Wheatley took the three points from the penalty.
Almost on the stroke of half-time, Dinnington had another player binned but this time Wheatley were off target.
Despite being two men down, Dinnington rallied and in injury time won themselves a penalty that Chris Williams sent through the uprights and Dinnington led 13-6.
Wheatley made a strong start to the second half, with their men advantage, and after sustained pressure it was not much of a surprise that they levelled the scores.
The hosts missed a kick at goal with 10 minutes to go which would have put them in the driving seat.
Two minutes later, Dinnington probably thought they had put themselves in a winning position when John Marshall touched down, and Williams converted.
However, with a minute on the clock the home full-back broke from deep inside his own half and made 70 yards before Wheatley recycled the ball to cross for a converted try to level the scores.
On Saturday Dinnington travel to West Hartlepool.
