Luis Palma has dealt Celtic another injury blow.

The Scottish Sun reports that the Honduran has picked up a knock in training. 

The £4m winger played no part in yesterday's 4-2 Scottish Cup quarter-final win over Livingston.

And it's said that Palma is now a doubt for this weekend's home game against St Johnstone, with the attacker now potentially out until after the international break.

Brendan Rodgers is hopeful to have Palma involved on Saturday, but the boss will take no chances with the 24-year-old.

Callum McGregor and Cameron Carter-Vickers are already injury concerns for the champions. 

And with the derby against Rangers looming on Sunday, April 7, the club will be doing all they can to ensure their big game players are ready for the encounter at Ibrox.

It's believed that both of those players will be missing until at least the Livingston game, this time in Premiership action, on Sunday, March 31.

In some good news though, the report states that Reo Hatate is making good progress after six weeks of rehabilitation following his calf injury picked up on international duty at the Asian Cup.

On McGregor's injury, Rodgers said post-Livi: “It always is if you have your top players and your captain not available.

“Of course, there will be other players who can come in, but the level that he brings the game to is beyond what a lot of our players can do. Fingers crossed again we can get to the bottom of that and he’ll be available after the international break.”

On CCV, he added: “We were just going through something very light on Saturday and he felt something in the back of his leg.

“He was okay to continue training but we just didn’t want to take any risk whatsoever with him. As much as he wants to play every game and be there, we had this earlier in the season when he said he was okay, but we ended up losing him for a number of matches.
