West Bromwich Albion are facing a potential goalkeeping crisis after Ben Foster injured his knee playing with his son and back-up Boaz Myhill injured his leg in the 1-1 Premier League draw with Leicester City on Monday.

Myhill got his first league start since the 2015-16 season after first choice Foster was ruled out of the game at the King Power Stadium by a knee injury sustained in rather unusual circumstances.

The 34-year-old was enjoying a kick-about with his son in the back garden when he injured his knee, ruling him out of the Leicester game.

With Foster having missed 10 months because of a cruciate ligament injury in 2015, West Brom manager Tony Pulis took a cautious approach to his team selection.

"There was no way in a million years we were going to take the risk with him tonight," Pulis said.

"He was playing with his son in the back garden and he just tweaked his knee and because he's had the cruciate we are a little bit concerned."

Myhill collided with Leicester striker Jamie Vardy in the second half of the match and the 34-year-old admitted it had been struggle to get through the rest of the game.

"We only have two experienced goalkeepers so we are a little bit short," Pulis said.

West Brom's other goalkeeping option is 21-year-old Alex Palmer, who has not made an appearance for the club yet.

West Brom, who are 10th in the league with 10 points, face tricky away games at Southampton and league leaders Manchester City this month.
