Former manager Lee Clark says he is keeping an eye on more Huddersfield Town products for possible loans to Kilmarnock.
The Scottish club are bossed by Clark, who last week snapped up Flo Bojaj and William Boyle on loan until January.
And Clark – who guided Town to their record unbeaten league run of 43 matches – said: “Young Jake Charles is a boy I know well from my time there.
“He was at the club as a young schoolboy and we had high hopes for him, so I’ve been watching his development.
“But there are other players there at the club who I will be keeping an eye on for future reference.”

Clark is preparing Killie for the new Scottish Premiership campaign after keeping them in the top flight last season.
The Rugby Park side beat Championship team Falkirk 4-1 over a two-legged play-off.
Centre-back Boyle, 20, has just agreed a new contract which runs until 2017, with Town having the option of a further year.
He has made two appearances from the bench as well as having loans at Kidderminster Harriers, Macclesfield Town and York City.
He qualifies for Scotland through his father, and attended a national Under 18 training camp back in 2012.
Former Albania junior international Bojaj, also 20, has made eight Town appearances, all as a substitute.
His first goal came in the 3-1 home Championship win over Reading in March.
Last October, he signed a new contract until 2017, with Town having the option of a further year.
Born in Kosovo, Bojaj was brought up in Borehamwood in Hertfordshire and joined Town’s junior set-up in 2013.
Both he and Boyle featured for the Under 21s in their Professional Development League II play-off final win over Sheffield United at Bramall Lane in May.
