One door shuts, another door opens for Tyrell Sloan, the out-of-favour fullback set to finally earn a recall following an injury to Cody Ramsey.

The Molong product suffered a knee injury in their win over Manly on Friday night, Dragons staffers hopeful it's just a medial ligament injury as they await results on the scans.

Enter Tyrell Sloan.

The fullback started the opening three games of the season, yet has only played one NRL game since due to a mixture of poor form and Cody Ramsey playing in career-best fashion, leaving Sloan to play NSW Cup.

Sloan still turned out for the Dragons reserve grade side on Saturday, playing on the wing while 21 year-old fullback Treigh Stewart scored a hat-trick against Newcastle.

During the post-game press conference, head coach Anthony Griffin explained his hybrid fullback approach, an option he could opt for against the Cowboys next week.

"We just switched Moses (Mbye) back to left centre in attack and let Birdy roam, which just suited him a little more in attack. And then Moses took the high balls.

"We have Sloany there as well. We'll have a look at our options after tomorrow."

Griffin also stated Sloan had only been moved to the wing in NSW Cup as injury cover for first-grade, and was still viewed as a fullback long-term.

"Last week was his first game back on the wing. When we lost Ravalawa, we thought we would put him there to school him up that way.

"It was to give him some football on the right wing last week and see if we can get him ready to play there."
