The severity of Daniel Sturridge's latest injury should be revealed in the coming days, as the Liverpool forward gets set to undergo scans on his foot.
Sturridge, who was a surprise exclusion from Liverpool's squad ahead of the team's Europa League fixture with Bordeaux on Thursday, suffered the knock during shooting practice and appears to be a doubt for Sunday's match against Swansea City.
Manager Jurgen Klopp was unable to give a proper update on his striker, since the injury occurred during training.
"It's not a situation I saw," Klopp said. "We trained in two groups with the starting lineup and the other players. They were shooting. We can now start thinking about it - it was really close to the game. But there's no news at the moment - we have to wait."
Sturridge recently returned to the squad following a long layoff because of a knee injury. He was included in Liverpool's squad for its win over Manchester City, but was an unused substitute.
