Caton missed most of the last season with a knee injury and his contract was due to expire at the end of June, but it's been extended until February 2007 to give him a chance to prove himself.
Caton said: "I have been working hard and in the gym four to five times a week as well as other fitness work. I have had a bit of rest as well, which is important, but hopefully I can hit the ground running later this week.
"The new management will have a great influence on the squad, I am sure of that. They have a tremendous amount of experience and I'm sure there will be lots to learn.
"The season ahead is a fresh start for me and I cannot wait to get things under way,"
