Linfield boss Warren Feeney secured the future of a posse of his players prior to the game against Portadown.
Goalkeeper Ross Glendinning agreed a new two-year extension to his current deal along with defensive pair Niall Quinn and Mark Haughey, midfielder Ross Clarke and striker Andy Waterworth.
"I'm thrilled to have tied some of the boys down to longer contracts, but that's just the start because we've got the nucleus of a squad here," said Feeney.
"There will be more to come. I want to build on what we've got here."
Glendinning, who rescued Linfield at the death with a crucial penalty save from Ross Redman, said: "I'm delighted to have signed a new contract with the club.
"The gaffer spoke to me on Thursday night and said he, the board and the Team Committee wanted to offer me a new two- year contract extension and I'm absolutely delighted.
"I didn't give it a second thought. I just signed it there before today's game and I'm really happy, as it means I can look to and plan for the future. I just want to concentrate and put all my efforts in to continuing to improve.
"I'm glad to have my future sorted out now, as it's good to get it out of the way. I'm still very young and I can now focus totally on playing and improving and helping the team to do well.
"The gaffer wanted to get the future of a few players sorted out and as you can see today, he's started to do that and hopefully, I can repay the faith he's shown in me with continuing good performances for the club.
"I'm delighted for Niall, Ross, Andy and Mark that they've got their contracts as well. Ross Clarke and Niall Quinn are the same age as me and we all came up through the youth ranks together and today it's nice that we've all signed new contracts on the same day as each other."
