GREEN BAY, Wis. -- A Fox sideline reporter said during Sunday's game that Packers left tackle David Bakhtiari forced his way back on to the field for a play while being evaluated for a concussion during the team's 23-20 loss Sunday to the San Francisco 49ers.
Reporter Pam Oliver said Bakhtiari took part in an extra-point attempt after getting hurt during a play on which teammate John Kuhn scored on 1-yard touchdown run with 12:06 left in regulation.
Bakhtiari was then taken to the locker room for further evaluation. He was eventually diagnosed with a concussion and did not return.
Spokesmen for both the NFL and the Packers said they were looking into the report.
The NFL is very strict on having teams follow a concussion diagnosis protocol once a player is suspected of having such an injury.
