However, Kent, who trail the Championship leaders Glamorgan by a point in second place, have been encouraged in their chase for the title by Surrey's list of injured bowlers.
Chris Lewis, who has made progress after a hip injury, faces a fitness test but, if he fails, Ben Hollioake and Joey Benjamin will share the new ball.
By contrast to Surrey and Kent, Glamorgan are at full strength against Somerset at Taunton and relishing the opportunity of winning their first title since 1969.
"It's a help psychologically to know it is in our hands. I would prefer to be in this position than to have to try and catch up," Matthew Maynard, the Glamorgan captain, said.
