Earlier in the season, when he had a full squad to choose from, Horne called for those players not in the team to continue to work hard in training and be ready to come into the side and make their presence felt.
Jones-Bishop has done just that and looks set to retain his place in the side to visit London Skolars on Saturday.
Not only did he score for the third successive game in Sunday’s top-of-the-table defeat against Bradford Bulls at the Keepmoat Stadium, he again showed his much-improved defensive skills.
“We’ve got a big squad, especially when you take into account the dual registration players,” said Jones-Bishop.
“There was a lot of competition for places at the start of the season so I had to be patient after losing my place after the first two games and try and take my chance when it came again.”
'Bish' as he is known, is the brother of fleet-footed Super League star Ben Jones-Bishop.
“Ben takes an interest in my career, as I do his, and we have a chat about things,” he said.
“He doesn’t give me any tips as such, just general advice such as concentrate on my game and don’t worry about other people.
“I’ve still got things I need to work on but I feel that I’m learning more about the game every week as should be the case.”
The Dons, who dropped from top to third as a result of Sunday’s defeat, will be aiming to bounce back against Skolars.
“You have to take it on the chin when that happens, learn your lessons and look to bounce back the following week which is what we’ll be hoping to do against London this weekend,” said Jones-Bishop.
“It’s a game we definitely need to be winning and we’ll be looking to be more clinical than we were against Bradford.
“We’ve also got to play our game and not let ourselves get dragged into a style of rugby which suits them better.”
It will be a first visit to the New River Stadium for some Dons players.
“I played there when I was at Oxford last season so I know what to expect,” said Jones-Bishop.
