San Francisco 49ers safety Eric Reid stayed on the ground grabbing his leg after a collision with Tennessee Titans wide receiver Kendall Wright in the fourth quarter of today's game.
Reid was able to walk off of the field with a little help.
Reid, a rookie, was drafted by the 49ers in the first round of this year's NFL Draft. Prior to leaving the game, he had one tackle and one assist against the Titans.
UPDATE:
Eric Reid returned to the game late in the fourth quarter.
