Two NRL rivals leading race for Rabbitohs fullback 

Rabbitohs fullback Alex Johnston is reportedly being closely monitored by Melbourne and Manly as his future at Redfern remains in the balance, per News Corp.

The out-of-contract winner has been in stellar form this season, but remains a chance to depart South Sydney in a move to a rival NRL club.

While there is a strong chance Johnston remains with Souths, both the Storm and Sea Eagles are now placed as serious candidates for the 25-year-old.

The Rabbitohs are preparing a monster contract for teenage sensation Joseph Suaalii for next season, with the club hoping to save enough salary space to secure the 17-year-old.

What this means for Johnston's future remains unclear.

The Rabbitohs flyer will return to face Melbourne on Friday night after sustaining a concussion against the Sea Eagles a fortnight ago, missing the club's Parramatta clash in the meantime.

With the Storm sett lose Josh Addo-Carr and Suliasi Vunivalu at the conclusion of the season, Johnston is positioned to be the perfect replacement at fullback for Melbourne.
