Porter collided with Bucs wideout Mike Williams on a first-quarter pass breakup in which both players went down but Porter appeared to take the worst of the hit. Porter initially rose to a knee but was kept down on the field by team medical personnel and later was immobilized on a backboard and loaded on a cart to be taken off the field as a precaution.
Porter was hospitalized, and Payton told reporters after the game that information regarding Porter's status was "good news." Porter similarly was upbeat on his Twitter account.
"This is why I love the #WhoDatNation," he wrote. "We are one big family. I'm doing good u guys, I look forward to being back soon. I love u guys."
