Jonny Evans to undergo groin scan

West Bromwich Albion manager Tony Pulis has revealed that Jonny Evans will undergo a scan on his groin after picking up an injury during his side's 1-0 defeat at the hands of Southampton this evening.

The 29-year-old lasted a little more than half an hour at St Mary's before limping off to be replaced by Allan Nyom, leaving him as a doubt for Northern Ireland's World Cup qualifying playoffs against Switzerland next month.

The severity of the injury is not yet known, but Pulis hinted that he fears Evans may face a while on the sidelines with the playoffs just 19 days away.

"Jonny's [injury is his] groin, so we're not sure until we scan it tomorrow," he told reporters,

"Obviously everyone in Northern Ireland will be a little bit concerned about Jonny, and we are a little bit concerned."

Northern Ireland host Switzerland in their first playoff on November 9 before playing the return leg three days later.
