Derbyshire are remaining hopeful that wicketkeeper Tom Poynton will return from injury to face Kent this week.
Richard Johnson had his loan cut short by Warwickshire this week following an injury to Tim Ambrose.
The Division Two leaders hope Poynton will play in Thursday's Championship game, but Tuesday's CB40 match against the Spitfires is probably too soon.
"We're gradually easing Tom Poynton back into action," said Derbyshire head coach Karl Krikken.
"There's every chance he will make it to fitness in time for the Championship match.
"If that's the case, I'd have no issues handing the gloves to Chris Durham for the 40-over match. He's done himself proud so far.
Durham wore the gloves for last week's draw with Australia A, taking a catch and a stumping and scoring an unbeaten 12 in Derbyshire's second innings.
"But if a full recovery for Tom starts to look unlikely, we will move to bring in a more experienced alternative ahead of the four-day match," added Krikken.
"Wicketkeeper is a specialist position and each county can only pick one, so there are always a few options to consider.
"It's a shame Richard Johnson's spell with us was cut short but we thank him for his contribution, particularly in scoring a brilliant 79 against Yorkshire."
