League: Panthers sign Isaac John from Super League

Penrith have signed former Warriors halfback Isaac John for the 2013 NRL season.

John links with his old coach at the Warriors, Ivan Cleary, and arrives at the Panthers after playing only 14 games in just over 12 months for UK Super League team Wakefield.

The 24-year-old joined the Wildcats on a three-year deal from the Warriors for the start of the 2012 season but failed to cement a spot in the team.

The signing bolsters the Panthers' halfback stocks with Luke Walsh and Tom Humble at the club.
