Barnet boss Lawrie Sanchez has paid tribute to his young loanees for their impact at the club.
Sanchez moved for Reading defender Michael Hector, 19, and 20-year-olds Paul Downing of West Brom and Southampton's Jack Saville after a spate of injuries at Underhill.
Saville and Downing started at Bristol Rovers on Saturday and Hector came on after Dennehy was struck down by the injury curse, and all three helped the Bees to a vital 2-0 win to edge them out of the relegation zone.
"Darren Dennehy, who is our main centre-half, went down injured at half-time but I thought Downing, Hector and Saville have been what has changed at this club," said Sanchez.
"They have come in have given us something extra."
