SAINTS manager Russell Martin is waiting for more information on Kyle Walker-Peters' injury after the full-back was forced off against Liverpool.

The two-time England international managed less than 20 minutes, having been introduced in the second half, before heading straight down the tunnel.

Walker-Peters was replaced by Taylor Harwood-Bellis straight after Liverpool's second goal, scored by 18 year old Jayden Danns.

The 26 year old is the only outfield player to play every minute for Saints in the Championship this season - a record which could come to an end on Saturday at Birmingham. 

Asked for an immediate update on Walker-Peters' fitness, Martin told the Daily Echo: "He has felt something.

"We will have to assess it and see where we are from there. It was a weird one because nobody knew he was going to come off.

"It is frustrating and hopefully, it is nothing too serious. We will know a little bit more in the next day or two."

Southampton lost their edge as the game progressed and Martin alluded to fatigue being a key factor behind that.

"I would put it down to energy," he continued, when asked why he felt Saints allowed the game to get away from them. 

"We had a bit of fatigue. We made some subs and then Kyle had to come off."
