Joe Burrow quickly took the blame for the Cincinnati Bengals' 16-13 loss to the Los Angeles Chargers on Sunday.
The rookie quarterback gave himself a "D" despite being one play away from scoring the game-winning touchdown in the closing seconds.
A missed 31-yard field goal in the final seconds prevented Burrow and the Bengals from forcing overtime.
"At the end of the day, I made too many mistakes for us to win the game and we didn't make enough plays," the quarterback said.
