Middlesbrough forward Patrick Bamford was stretchered off in a neck brace on Saturday afternoon after a collision with Bristol City's Aden Flint.
City traveled to the Riverside Stadium desperate for a victory hoping to keep their hopes of making this year's Championship play-offs alive, while a win would move Boro into the top six.
The game was tied at 1-1 after Milan Djuric 13th-minute strike was cancelled out by Boro's George Friend.
With less than 10 minutes remaining in the first-half, however, the matter at hand was put to one side as Bamford was grounded after colliding with Flint in an aerial challenge.
