Australian prodigy Daniel Arzani has been named in Celtic's 24-man list for their UEFA Champions League qualifier against FK Sarajevo on Wednesday (AEST).
The 20-year-old hasn't played a senior match since rupturing his anterior cruciate ligament during his Hoops league debut against Dundee FC in October last year.
While Arzani will be unlikely to start the match at Sarajevo's Olimpijski Stadion, it's a good sign for his prospects at the club with his inclusion in the squad.
Fellow Australian Tom Rogic was also named on the list as Celtic bid to negotiate three rounds of playoffs to qualify for the group stage of the Champions League.
Arzani is yet to establish himself at Hampden Park since joining on two-year loan deal from English giants Manchester City at the start of last season.

After taking the time to settle in the club's reserves team, Arzani earned his senior opportunity with a substitute appearance in the league, but he only lasted 23 minutes before suffering the season-ending knee issue.
The injury kept him out of Australia's Asian Cup campaign in the UAE in January, where the flying winger was tipped to be an important part of the Socceroos' title defence.
Arzani first excelled for A-League club Melbourne City after being developed and introduced to the first team by former Manchester United youth coach Warren Joyce during the 2017-18 season.
His domestic form ensured he was selected for Australia's World Cup squad where he made three substitute appearances in the group stage as an impact player.
The attacker recently committed his future verbally to the Scottish champions and spoke of encouraging talks with the club's coach Neil Lennon.
