Defenseman Nick Leddy said he spent time in Rockford "working on plays in the corner and being better in front of the net."
Leddy did enough to warrant more time with the Hawks with Jassen Cullimore sent down, Nick Boynton struggling and John Scott a better fit at wing in the Hawks system.
"He's played well there all year," coach Joel Quenneville said. "He's even looked bigger to me off and on the ice. The World Juniors was good for him as well.
"He played well when he was here earlier. The consistency is something he added as he worked his way down there."
Quenneville said he liked what he saw from Leddy and defense partner Jordan Hendry Friday against the Senators. Leddy was on the ice for 15:41 on Friday with two shots.
"[Leddy] did a nice job," Quenneville said. "I thought that was a good pair for us [with Hendry]. They skated out of trouble, and had good patience in the offensive end."
Leddy made the Hawks out of training camp, benefitting from an injured Brian Campbell, and played in six games before being sent to Rockford.
The 19-year-old just won the bronze medal with Team USA at the 2011 World Junior Championships in Buffalo. He had two assists and a plus-1 in five games.
"It was an awesome experience," Leddy said. "It was something I'll never forget."
