Substitute Joel Bradley grabbed a late point for Coleraine to make it three draws on the bounce for Oran Kearney’s side.
Both managers were disappointed not to have taken victory in what was the proverbial game of two halves, but they reflected that a stalemate was a fair reflection on both sides’ performances.
Glenavon player/boss Gary Hamilton thought David Rainey had scored a wonderfully taken winner seven minutes from time, but Bradley was in the right place to score a vital equaliser in stoppage time.
“To concede a goal at 2-1 up you’re always going to be disappointed,” said Hamilton.
“Coleraine were the better team by a mile at half time. We have a lot of experienced players in the dressing room now and we asked questions of them to see where we needed to change things.
“We asked the boys to get the ball down and play football, and so it proved that we dominated the second half.”
Stephen Carson went wide with an early free kick, before the Bannsiders took the lead on six minutes through Gary Browne.
He was allowed the freedom of Mourneview Park, waltzing through the Glenavon defence and firing into the bottom right-hand corner.
The could half had an identical second goal shortly afterwards through Gareth Tommons, but he opted to shoot wide of the left post.
But the hosts persevered and got a goal, very much against the run of play, when Rainey found Guy Bates to slot past Wayne Drummond.
And in the second half they were like a totally different team. Ciaran Martyn hit the upright after a Kyle Neill corner led to a goalmouth scramble.
Rainey thought he had won the game with a wonderfully taken on seven minutes from time. Glenavon broke down the left and the former Crusaders front man’s initial shot was blocke. He composed himself for a second try and curled a wonderful shot into the top corner.
But Glenavon were to be denied in stoppage time as Jennings’ initial pass was parried into the path of substitute Bradley to sidefoot home.
“In previous weeks we have been guilty of not starting well, but this week it was the exact opposite,” Coleraine boss Kearney said.
“We dominated the first half and had some good opportunites and we should have been two or three goals up at half time.
“But a goal towards the end of the first half in that manner is always going to be a blow and we knew what was going to come in the second half.”
