CSL's Goulart leaves the squad, leaving the team with only one foreign player.

Celtic striker David Luiz has been ruled out for the rest of the season after undergoing surgery on his knee injury.

The Brazilian international was forced to leave the pitch in the first half of Celtic's 1-0 defeat to St Johnstone on Saturday following an incident during the match.

He had been replaced by substitute Jamie Murphy and will now be sidelined until at least the end of March.

However, there is some good news for fans as defender Callum Paterson has been called up to the Scotland national team for their friendly against France next month.

Paterson, who joined Celtic from West Ham last summer, has been included in the squad for the game at Hampden Park on February 25.

This means that he will miss Celtic's next two games against Kilmarnock and Hibernian, but should return for the home clash with Dundee United on March 7.

In other news, midfielder Stuart Armstrong has also returned to training after suffering an ankle injury earlier this week.

Armstrong, who was originally expected to be out for three weeks, has been given the all-clear to play again and could feature in Celtic's next match against Aberdeen on March 8.

Overall, it looks like Celtic have a strong squad heading into the final few months of the season, with plenty of players returning to fitness and ready to compete for places in the starting line-up.
