Atlanta Falcons left tackle Sam Baker injured his right knee and was carted off the field.
He tore his patella in his left knee last season.
This is regarded as a serious injury.
“We’ll have more information in the next 24 hours,” Falcons coach Mike Smith said. “And as soon as we do, we’ll let you guys know.”
The Falcons could shift rookie Jake Matthews to the left side.
They also have Lamar Holmes.
