Celtic defender Cameron Carter-Vickers was missing from training on Friday.

The United States defender was not involved with his team-mates at Lennoxtown ahead of Saturday's match against St Johnstone.

It's unclear whether Carter-Vickers has been given extra time off or whether there is concern over an injury issue. Alistair Johnston was back in training.

Brendan Rodgers has previously given players more recovery time or altered sessions to keep the squad in top condition throughout the season.

Speaking last week, Rodgers said: "We've got a few players with niggles so we will have a look at that and assess that by end of play tomorrow. We won't take any risks with one or two.

"It was the second day of recovery as well so there was a group of the players out recovering and a group training hard and then one or two inside just making extra recovery inside rather than out."
