The forward was left in a heap after an aerial challenge with man mountain Flint just before the hour mark in the game, which could have a huge impact on the Championship play-off race.
Bristol City players quickly gestured for the medical staff, who spent some seven minutes attending to the 24-year-old on the pitch, before removing him on a stretcher, with his neck in a brace and being administered oxygen.
There was a collective intake of breath around the Riverside as the forward was carried off the pitch and replaced by Britt Assombalonga.
Bamford had scored nine goals in 10 games ahead of the Bristol City game and Boro boss Tony Pulis will be hoping the injury is nothing serious, with Assombalonga the club's only other recognised senior striker, with Rudy Gestede out for the season and Martin Braithwaite and Ashley Fletcher out on loan at Bordeaux and Sunderland respectively.
The injury led to 11 minutes of added time being signalled at the end of the first half.
