NEWCASTLE fans will be smiling from ear to ear at the sight of Mitchell Pearce in their famous red and blue colours.

The Origin halfback appeared on Monday wearing the Knights kit for the first time, after signing with the Hunter club on Thursday.

He turned out for his first training session with his new teammates and spoke to media about his switch from the Roosters.

We know, it’s a little strange seeing Pearce in anything other than the tricolours of the Roosters.

Round 20

And it could take a little getting used to.

Here’s some of the big-name off-season switches and what they look like in their new strip.
