West Ham United: Enner Valencia to have knee scan

West Ham Enner Valencia will have a scan on his knee after being carried off on a stretcher during his team's Europa League tie with Astra Giurgiu.

The 25-year-old Ecuador forward fell awkwardly during a challenge soon after heading his side ahead in the third qualifying round first leg tie.
"I am worried," said Hammers manager Slaven Bilic after the 2-2 draw.
"It looks serious but we won't know for sure until he has a scan. This is the reason I am unhappy."
Valencia's injury capped a bad night for West Ham, who face a battle to stay in Europe after conceding a 2-0 lead at Upton Park.
Mauro Zarate added to Valencia's goal but a red card for defender James Collins turned the game.
Astra, who host the second leg on 6 August, hit back through Fernando Boldrin's effort and an own goal from debutant Angelo Ogbonna.
But it was Valencia's injury that concerned Bilic the most.
"I am not happy with the result of course but this is not as important as the injury," added the Hammers boss, who was ordered away from his technical area in the closing stages after rowing with officials.
West Ham qualified for the Europa League through the Fair Play League but Collins' dismissal in the 59th minute means they have now had three players sent off in five Europa League games.
Forward Diafra Sakho was sent off against Lusitanos in the first qualifying round while defender James Tomkins was suspended against Astra after being red carded in Malta.
