Messi doesn't take part in training and may miss Bilbao trip LaLiga Santander - Barcelona Umtiti is back with the group

There was good news and bad news for Barcelona at their Friday training session.

The good news was that Samuel Umtiti took some part in the session as he works to return from his knee injury, but the bad news was that Lionel Messi didn't participate.

The Argentine has been struggling with a knock for a few days and seemed to feel the effects of it when he came on during the midweek Clasico, which is leading Barcelona to proceed with caution.

It'll be difficult for him to be back and ready in time for Sunday's match against Athletic Club, while Umtiti should also miss this game.

The French defender is instead targeting a return against Lyon in the Champions League.
