London - Wales are considering citing England flanker Tom Wood after his stray boot struck Welsh fullback Liam Williams on the head during their 28-25 Rugby World Cup win at Twickenham, defence coach Shaun Edwards said on Sunday.
Williams will go through concussion protocols having been carried off on a stretcher following the incident, which could add to Wales' long-list of injuries.
"There was definitely contact between part of Tom Wood's body and Liam's head. It is something we are going to look at, with regards to citing. But we will make a comment on that later on. It is clearly obvious there was some contact with the head," Edwards told a news conference.
"The decision will be made by our manager after discussions with (coach) Warren (Gatland, but we did lose one of our best players in a position where we are quite short at the moment."
With key backs Leigh Halfpenny, Rhys Webb and Cory Allen already on Wales' casualty list, winger Hallam Amos suffered a dislocated shoulder and centre Scott Williams a knee injury during the bruising encounter with England.
"We have some injuries once again. We will have more of an idea where we are tomorrow. Hallam Amos and Scott Williams are definitely the biggest concerns, long term," Edwards said.
"The resilience shown by these players means that if we have another player or two out of the World Cup, someone else will step up and perform like we did last night. But at the moment, there is nobody definitely out.
"However, potentially we could lose more, there is no doubt about that. But we just have to keep showing the resilience we have shown so far in the competition."
Wales face Fiji on Thursday, knowing that a win could assure their place in the knockout stages. England have to beat Australia next Saturday to stay in with a realistic chance of getting out of the group.
