Town have signed Luke Matheson on loan from Wolverhampton Wanderers.
Matheson joined Wolves from Rochdale in January 2020 for a fee of around £1 million having made a big impact as a youngster at Spotland after making his debut aged 15 years and 336 days.
He made national headlines when he netted the leveller for Dale in a 1-1 Caraboa Cup draw over 90 minutes with Manchester United at Old Trafford, taking the tie to penalties before his side were beaten.
Matheson, now 18, who is 5ft 6in tall, rejoined Dale on loan for the rest of the curtailes 2019/20 campaign following his switch. He has spent this season at Molineux but has featured only for their U23 side having suffered an ankle injury in pre-season.
The Blues have been short of a right-back with Kane Vincent-Young still to return from the achilles injury he suffered in pre-season, while Janoi Donacien has moved on loan to Fleetwood with manager Paul Lambert having rarely used the former Accrington man.
Skipper Luke Chambers has filled in in the role but with central defence the 35-year-old preferred position.
Matheson's addition may lead to worries that Vincent-Young's return may not be as close as had been hoped with the former Colchester man thought likely to play a game, either for the U23s or an in-house match, this week.
Fallowfield-born Matheson's move to the Blues may be seen as something of a surprise as he is a Norwich fan, his father hailing from Norfolk.
Matheson, who has won England caps at U17 and U18 levels, is the Blues’ sixth loanee with only five allowed in a matchday squad.
