Mikey Johnston suffered a groin injury during the 2-0 win at Ibrox on September 1 and will miss Saturday’s match after being withdrawn from the Scotland u-21 squad.
Morgan was on the bench at Ibrox, Hayes came off the bench to score while Elyounoussi would have been given some promises of first team football in exchange for leaving Southampton behind for a season.
The plastic surface at Hamilton will come into consideration but after the derby success Lennon will be keen to kick on from that result.
There are decent cases to be made for including any of the three players listed with competition getting tight for a place on the bench after the additions made towards the end of the transfer window.
Injuries will play a part in deciding who will play in defence with Kris Ajer the main concern, if fit the Norwegian is likely to play alongside Christopher Jullien, if he’s not ready Hatem Abd Elhamed will play a more central role allowing Moritz Bauer to start at right-back.
