Sheffield United have recruited two young players on one-year contracts from other clubs' academies.
Australian-born midfielder Kyle Nix, 19, joins from Aston Villa and is an England Under-19 international.
Republic of Ireland Under-21 striker or centre-back Gary Mulligan, 20, was just released by Wolves and had a loan spell at Rushden & Diamonds last season.
"This is a great opportunity for both lads, who have shown promise," boss Neil Warnock told the club website.
"I have watched Mulligan a few times and he was the best player on the park in those games, while Nix did well when we had him at the end of last season."
The Blades have also offered professional contracts to six players from their own academy - Stephen Quinn, Travis Binnion, Ryan Gyaki, Colin Marrison, Kyle McFadzean and Nick Travis.
