Celtic have until 10:59pm UK time on Tuesday night to potentially strengthen Martin O’Neill’s squad for Wednesday’s huge Champions League clash with LASK.
The countdown is now on.
UEFA regulations allow Celtic to register a maximum of two new eligible players after the original List A deadline for the play-off.
Crucially, those additions must be registered by 23:59 CET on the day before the first leg.
That converts to 10:59pm UK time on Tuesday, August 18.
With LASK arriving at Celtic Park on Wednesday night, it gives Celtic one final opportunity to bolster O’Neill’s European squad.
Celtic transfer deadline opens door for two additions
The rule could become particularly significant given Celtic’s continuing activity in the transfer market.
Any new arrival would need to be properly registered and eligible to represent Celtic before being added to the UEFA squad.
One player worth watching is Niko Sigur.
The 22-year-old Hajduk Split midfielder has been strongly linked with Celtic, while reports suggest the Canadian international is keen on making the move.
Whether negotiations can move quickly enough remains to be seen. However, the UEFA deadline adds another layer of intrigue to the next 24 hours.
Gvidas Gineitis is another midfielder who has been linked with Celtic.
Competition for the Torino player could complicate matters, but Celtic’s ability to add two players means supporters will be watching developments closely.
Celtic face a race against the LASK clock
There is no requirement for Celtic to use either additional registration place.
However, completing even one signing before Tuesday night could potentially hand O’Neill another option for Wednesday.
That makes 10:59pm on Tuesday the crucial moment.
After that point, the opportunity to add these two late players for the first leg closes.
Celtic therefore have a small but potentially important window to strengthen before one of their biggest games of the season.
The transfer clock is ticking — and Tuesday could now become a very interesting day at Celtic Park.

All in plenty of time for kick off ! I keep hearing that old Beatles song in my head …you know the one called ‘Help !’ It’s very catchy …..
Do your homework.
