Scottish giants, Celtic, will return to feature in the Champions League despite a heavy 6-1 aggregate loss to Legia Warsaw, The Independent reports.
Legia's storming victory over Ronny Delia's side has been overturned by UEFA following a breach of rules in which the Polish hopefuls fielded an ineligible sub in the form of Bartosz Bereszynski, who entered proceedings as an 86th-minute substitute in a 2-0 second-leg victory over Celtic at Murrayfield.
Bereszynski was sent off in Legia's final Europa League match against Apollon last season and missed Legia's second qualifying round victory over St. Patrick and the first-leg victory over Celtic.
However, it has since been ascertained that the Polish full-back was in fact not registered in Legia's squads, meaning the three-game suspension had yet to take effect.
Legia announced the pending investigation on their official website:
"The club announces that in connection with the Celtic FC-Legia Warsaw match in the second leg of the third qualifying round of the Champions League, Uefa opened an investigation into the participation of Bartosz Bereszynski.
"The club is preparing the relevant information and explanations, which will be sent to Uefa today (Thursday).
"The result of the investigation will be announced immediately after its completion."
This is not the first time the reigning Scottish premiers have benefited from overturned victories, with their restoration into the 2011/12 Europa League group stages when Swiss opponents, Sion, fielded five ineligible players.
Celtic were previously named in the Europa League qualifiers, however will partake in the UEFA Champions League draw on Friday morning.
