Horlin-Smith, who kicked the winning goal with just over 60 seconds left on the clock on Sunday, has had surgery after fracturing his thumb during the last gasp win, coach Chris Scott revealed on Wednesday.
“George Horlin-Smith unfortunately has had surgery on a fracture in his thumb. He’ll miss this week,” Scott said.
“It was actually the last contest. It seemed after the game it was something minor but as it turned out, he does need that week off.”
Meanwhile, Scott remains hopeful onballer Cameron Guthrie can return from a hamstring injury and play his first game for the season, while Sam Menegola and Jed Bews also impressed in the VFL and could be in line for a call-up.
“We’re optimistic without being sure yet,” Scott said of Guthrie.
“We had some pleasing performances [in the VFL]. Menegola, Smith were good. Bews will be in the frame as well.”
