Newcastle coach Sadler expects progress from Edgar, Carroll
"He may have had a disappointing time on loan at Preston, but his performances in the reserves certainly earned him that chance in the first team - and I know the manager had no hesitation in putting him in.
"David Edgar also got an opportunity. He really grabbed the reserve team by the scruff of the neck from Christmas onwards.
"Again, with Kevin coming in not long after, he put himself in the shop window by doing that and playing in that manner.
"He was aggressive, well organised and very much a leader on the pitch.
"There is a path there for all the players - they can all see that.
