Chelsea midfielder Oscar went to
hospital when club staff became "scared" about his condition after he
was apparently concussed against Arsenal, said manager Jose Mourinho.
Oscar collided with Arsenal goalkeeper David Ospina in
the 16th minute, but was only substituted at the interval.
"He went for a scan because we were a little
scared," Mourinho told Sky.
New rules mean the club doctor has the
final say on whether a player with a head injury should play on.
The Premier League introduced the regulation at the start
of the season, as well as bringing in a "tunnel" doctor who acts as
an extra pair of eyes to assess the severity of incidents on television
monitors.
Replays appeared to show Oscar exhibiting the
"fencing response" -involuntary
arm movements that are an indicator of concussion -
as he lay on the Emirates turf.
However, after a touchline conversation with Chelsea's
medical staff - including first team doctor Eva Carneiro - he returned to the
pitch.
Last season Tottenham were criticised for letting
goalkeeper Hugo Lloris play on in the goalless draw against
Everton after being knocked out in a collision with Romelu Lukaku in the 78th
minute.
Brain injury charity Headway said
Spurs were guilty of an "irresponsible and cavalier attitude".
Guidelines from the National Institute for Health and
Care Excellence state people should not play any contact sport for at least
three weeks after suffering a concussion.
