Biggar was fit to play on: Ospreys
The concussion protocols in rugby have again been thrown into question after Wales fly-half Dan Biggar confessed to being unable to remember his last-minute penalty miss during Ospreys' 20-18 PRO12 defeat by Leinster.
Biggar left the field in the 59th minute and was off for nine minutes as he underwent a pitch-side head injury assessment (HIA) at the Liberty Stadium.
Having already successfully slotted twice from the tee, Biggar stepped up again as the clock went dead but missed.
Biggar then confessed he could barely recall any of the last 10 minutes of the game, having returned from his HIA in the 69th minute.
"It was a disappointing way to end the game," Biggar said. "I can't really remember much of the last 10 minutes, to be honest. I was a little bit dazed."
Under the HIA protocol, as well as a balance evaluation and symptom assessments, there are a number of memory tests, for both long and short-term memory.
And, in a statement, Ospreys said they were "satisfied" that Biggar was fit to return to play and the HIA was conducted correctly.
"Dan left the field during the second half to receive medical treatment for an eye wound," the Welsh region said.
"Before being allowed to return to the field Dan underwent, and passed, a head injury assessment as per the required protocol and satisfied the medical team that he was fit to continue.
"Having resumed playing, Dan reported no further symptoms. After the match, Dan underwent a thorough assessment with the medical team, as is standard procedure for such occurrences, at which time they were made aware of his comments in an interview.
"Dan will continue to be monitored. He will need to pass each stage and satisfy stringent criteria before being ruled fit to play."
