The deal also includes the option of a further year, which could potentially keep the prop at the club until the end of the 2018 season.
“I am very happy to stay here especially as I have built up a great relationship with the rest of the squad and the coaching staff,” said Simon.
“It is a good opportunity for me. The club has grown over the past year and it is nice to know that I am part of Chris Chester’s plans for the future.”
Trinity coach Chris Chester is very pleased that the Frenchman has committed to the club.
“I am pleased that we have been able to secure Mika for another year,” he said.
“He is a fantastic player. He’s been a stand out performer for us this season and I am looking forward to see what else he has to show us over the next year.
“The main intention for the club is to keep all of our best players and I feel we are on the right path to do this.”
