Somerset captain Trescothick may be rested in CB40
Somerset director of cricket Brian Rose says Marcus Trescothick could be rested for next year's CB40 campaign.
Captain Trescothick turns 36 in December and next season will be his 19th term with the county.
"The problem with Marcus is that he loves to play cricket for Somerset," Rose told BBC Somerset.
"But we need to have an understanding as I want to prolong his career and I'm sure he does, so we'll have a look at how we can accommodate both things."
Trescothick, who retired from England duty in March 2008, has played 697 competitive games for Somerset, including 346 one-day matches.
And Rose admits he could be tempted to utilise the Somerset youngsters for the one-day competitions and focus the senior players' efforts on claiming the County Championship Division One title, which they have yet to win in their history.
"People might argue we haven't won a competition because we've arrived at finals, or the last couple of championships, knackered - we are having a look at that," said Rose.
"My own philosophy of turning out on the park and in an attempt to win every game is not going to change but we may have a look at who we are playing in the side.
"The key thing for the first-class cricketer is the Championship so we'll still be aiming to do that next year.
"The T20 is one competition and is completely separate. It's played in June so you can concentrate that with a special team.
