Sean Long's return to rugby league may be hastened after Salford youngster Marc Sneyd suffered ankle ligament damage in .
Long, who retired from the game a year ago, is assistant coach to Phil Veivers at Salford, but was re-registered as a player by the Reds earlier this month.
Veivers said the 35-year-old scrum-half would only feature "in an emergency".
Sneyd and Daniel Holdsworth have been their half-back pairing since Matty Smith's mid-summer departure to Wigan.
Salford fell to a second consecutive Super League defeat at the weekend, going down 34-26 at the KC Stadium.
