Hibernian moved quickly to replace John McGinn after signing former Rangers midfielder Emerson Hyndman on loan from Bournemouth.
The 22-year-old joined on a six-month deal just as McGinn completed his move to Aston Villa for a fee believed to be worth at least £2.75million.
The American could even make his Hibs debut in Thursday’s Europa League clash with Molde, if international clearance arrives in time.
Hibs earlier completed the signing of Thomas Agyepong from Manchester City but the Ghana winger is awaiting the outcome of a visa application.
Hyndman, who impressed during half a season at Ibrox following a loan move in January 2017, said: “I enjoyed my previous time in Scotland – my game is well suited to the style of play here.
“I’m looking forward to meeting up with the squad and hopefully working my way into the team.”
Hibs head coach Neil Lennon said: “We are pleased to bring in a player of Emerson’s quality. Technically he’s at a good level, he’s got experience of the Scottish game and gives us another option in the centre of midfield.”
McGinn has been a key player for Hibs in the past three years but Efe Ambrose has vowed to show they are no one-man team.
The defender said ahead of the first leg of the third qualifying round: “I don’t think it’s going to affect us. We are a team, not an individual. We know it’s been coming so we will just focus on the game, that’s the most important thing for Hibs.
“We know if John is here he is a plus for the team, he is a good player. So we are without John but we are still here and we still have the quality of player to do well.
“So we focus on the game and leave John to deal with everything that is going on around him.
“We wish him well but in football players come and go so we are not going to be distracted by his transfer.
“I believe in the squad, we have players who can come in and do well. Every team would want John in their team but we have played a couple of games without him and done very well so we will just focus on the game.”
Ambrose was on the losing side against Molde in the same competition three years ago as the Norwegian side completed a double over Celtic in the group stages, and the Nigerian warned Hibs will need to be on their guard against Ole Gunnar Solskjaer’s side.
“I know they are a kind of tactical team and they are disciplined,” Ambrose said.
“Sometimes you get out of possession and they counter you and they strike on you without you knowing.”
