Kilmarnock have snapped up Norwich City striker Ryan Jarvis on-loan.
Jefferies was delighted to land Jarvis and said: "He's done very well whenever I've seen him recently.
"It's good for us to bring a new face into the club and it's good for the boy to have a chance to play first-team football.
"You only have to look at the examples of Anthony Stokes and Kasper Schmeichel at Falkirk to see how a move like this can benefit clubs and players."
