The county were hoping to announce the signing of an international fast bowler but have been hampered by the reluctance of international boards to release players on the eve of the ICC Champions Trophy, which will take place in England in June.
To make matters worse, injuries to two shortlisted candidates have scuppered the club's plans, although Kent were in talks with another target this week.
Meanwhile, the club are hopeful that progress is being made in their bid to appoint an interim assistant coach – widely believed to be Jason Gillespie – before the start of the Championship season next month.
Kent have agreed terms on a short-term deal but the ECB are currently working on ratifying the coach’s visa and qualifications ahead of rubber-stamping the deal.
One new face at pre-season training, which began in Canterbury on Monday, was that of Joe Weatherley, a 20-year-old former England under-19s batsman who arrives from Hampshire on a year’s loan.
Head coach Matt Walker said: “It’s another fine young batter in the squad.
“I haven’t seen too much of him but he’s highly regarded by Hampshire. He’s organised, ambitious and is a good lad. He’s fitted in brilliantly.
“He has an experienced head on young shoulders and has captained England under-19s so he’s got a decent cricket brain.”
He added: “He adds to our batting unit. I know he’s a Hampshire player but I said to him he’s part of our squad and challenging for a first team place like all our players."
Walker claimed first XI places were up for grabs before the first Championship game at home to Gloucestershire on April 7, adding: “We have been a fairly settled top five for the past year but it’s not to say someone can’t force their way in.
“At the start of the year you want to have an open mind. I have no fixed idea in my head of what that first team will look like, that’s up to other people to push their claim. That’s what pre season is about.”
