Bradford City manager Peter Taylor has completed the loan signing of Watford teenager Rob Kiernan on a one-month deal.
Taylor has moved to boost a depleted back four by drafting in the 19-year-old central defender in time for Saturday's clash at Wycombe.
Steve Williams is sidelined with a groin strain, Shane Duff has been struggling with an Achilles injury, Simon Ramsden has been sidelined since mid-August with a long-term calf-injury and Robbie Threlfall returned to the substitutes' bench at Colchester last weekend after a nine-game absence due to a back problem.
Kiernan had a loan spell at Kilmarnock last season and earlier this season had a loan stint at League One side Yeovil Town, where he made three appearances.
The centre-half has also played for the Republic of Ireland's Under-19 and Under-21 sides.
