Jonathan Spector will sit out West Ham United's next two fixtures after suffering a head injury in the weekend win against Sunderland.
The US international was knocked unconscious midway through the second half of the 2-0 victory and required several minutes of treatment on the pitch before being taken to hospital. Although he soon came around, Spector was kept in hospital overnight before being released on Sunday morning.
Spector will spend this week at home recovering as is standard with all injuries of this nature before returning next week to Chadwell Heath for light work. He will miss out on the away matches at Tottenham Hotspur and Aston Villa over the next two weekends but could return for the home game against Chelsea on Saturday 25 April.
The 23-year-old had been in good form. He started the last two Barclays Premier League encounters, having come off the bench in the previous three fixtures. Spector had just returned from international duty, having been with the US national team for the World Cup qualfiers away to El Salvador and at home to Trinidad and Tobago.
