The veteran prop began the season with Bradford before joining Hull FC. He was released by the Black and Whites, and is no looking forward to helping Cas deliver some tangible success for the fans.
“I’m loving it here at Castleford Tigers, I knew a few of the lads beforehand so it’s been pretty easy settling in,” he said.
“They are a great bunch and everyone has made me feel really welcome. It’s a great old style club, the people here are so friendly and everyone here works together and believes in this great team.
“I’ve worked with Daryl before and when the opportunity came to work with him again I was delighted to take it. My wife is from Cas’ and her family are lifelong Cas supporters, so it’s ideal for me at this stage in my career to be able to play in front of them and make them happy.
“There is so much here to look forward to, we are in the prime position to make this a big season for this great club.
“People may have expected us to be fighting it out at the bottom but to be fighting it out at the top is great for the club and brilliant for the town and the people of Castleford.”
Tigers coach Daryl Powell is also pleased to have added the 33-year-old to his pack for the business end of the season.
“We are delighted to sign Garreth for the remainder of the season,” he said.
“He has fitted in very well into the club and his experience will be important for us as we lead into a crucial part of the season.”
