LASK are the opponents as Spurs prepare for their first of six European fixtures, having successfully navigated three qualifying fixtures in a gruelling start to the season.
Lo Celso missed the 3-3 draw with West Ham on Sunday but was back with the squad at Hotspur Way on Wednesday, along with Erik Lamela.
Harry Kane could make way in the starting line-up for summer loanee arrival Carlos Vinicius. Joe Rodon is ineligable for the Europa League.
Eric Dier, though, was absent with the hamstring injury sustained while on international duty, with Japhet Tanganga also sidelined with a thigh complaint.
