Brendan Rodgers says Greg Taylor isn't in Celtic's squad this evening because his wife has gone into labour.
The left-back started in a 2-1 defeat to Hibernian at Easter Road on Sunday, although he was hooked at the break.
Fast forward a few days, and Taylor isn't even in Celtic's squad to face Aberdeen in the Scottish Premiership this evening, with Crystal Palace loanee Jeffrey Schlupp coming in to take his place in the lineup.

Speaking to BBC ahead of this evening's game, Parkhead boss Rodgers explained Taylor's absence: "Greg was in the squad, and then late this afternoon when we were at this hotel, his wife went into labour," he said.
"We sent him away to be with her, and fingers crossed everything is OK for them, and they'll be parents for the first time."
The 27-year-old is out of contract at the end of the season and hasn't yet elected to prolong his stay in Glasgow's east end.
Kieran Tierney has agreed to return to Celtic in the summer, putting Taylor's long-term position at the club in jeopardy.
While his absence tonight is down to a family matter, whether he will remain at Parkhead past the end of the current campaign remains to be seen.
