concuss

The captain has little memory of watching those closing minutes, having been concussed in a clattering tackle.

They go on to say the match referee "should consider the likely role" the concussed player would have played during the remainder of the match and "the normal role" played by the replacement.

“Our members have been beaten, concussed, pepper sprayed, both by counter-protesters and by police forces. As a union, it is our responsibility to stand beside them,” the union said in a statement.

"I was concussed going into that fight - I fell down the stairs and knocked myself out two weeks before," she recalled.

The guidelines give a similar timeframe for a concussed athlete to resume light exercise — as long as their symptoms are stable and the effort does not make them much worse.
