Jacksonville Jaguars' Louis Rees-Zammit says he's moving on from the NFL and returning to rugby, via an announcement on his Instagram account on Thursday.

Rees-Zammit has announced his return to rugby at a time when the WRU is considering cutting from four professional teams down to three or two. Money is tight and Dragons, Ospreys, Scarlets and WRU-owned Cardiff will not be able to compete with other clubs unless there is special help from a governing body that has its own financial challenges.
