Rupert Lowe added: "Matt has had some injury problems so far this year and we are not in a position to identify a contract extension right now. It is going to be a matter for him and the club to decide what is in both parties' best long-term interests.
"Hopefully Matt will get fit and contribute later in the season, which culminates in his testimonial, which will be a super event.
"We might even achieve a record gate for that because there won't be segregation between fans.
"Matt has been a tremendous participant in the club's history but we've got to see what he does between now and the end of the season."
