SANTA CLARA, Calif. (AP) -Nose tackle Aubrayo Franklin left the San Francisco 49ers' practice field on a cart Monday with a knee injury.
Franklin, who left Baltimore to sign with San Francisco in the offseason, was injured when two offensive linemen rolled onto his leg during a play. He fell facedown, then rolled over holding his left knee while trainers huddled around him.
Coach Mike Nolan said Franklin sprained his knee but will undergo more tests.
``The fear would be it would be something other than a sprain,'' said Nolan, who coached Franklin when both were with the Ravens. ``It would be a piece of adversity, something we would need to do a good job responding to.''
Slated to start in the middle of the 49ers' 3-4 defensive scheme, Franklin's absence could be a potentially serious blow to the club's season.
Defensive lineman Ronald Fields, who might fill in for Franklin along with Isaac Sopoaga, spoke with Franklin after the injury.
``He said it's not really hurting him or anything,'' Fields said. ``When it happened, you should have heard him then. He was screaming.''
