Seattle Seahawks wide receiver Cady Johnson is in stable condition at a local hospital after apparently sustaining head and neck injuries during the preseason opener Thursday night.

Johnson, late in the first half of the Seahawks’ game against the Minnesota Vikings Thursday night, was seen walking to the medical tent behind their bench at Lumen Field. Nothing great happened on the field, and he didn’t need help getting up or out.

Shortly afterwards, Johnson was carried off the field with his head and neck pinned.

Johnson was rushed to an ambulance and taken to a local hospital, which the Seahawks quickly said was taken “as a precaution” for head and neck injuries. Other details are not known, although it is in stable condition.

Johnson last touched the ball during a kickoff in the second quarter, and he fell hard on the play, but got up and continued the play. He was targeted twice in Thursday’s pre-season game, but was unsuccessful. He carried one for two yards.

Johnson is entering his second season with the Seahawks. He had two receptions for 21 yards in three games last year. The 25-year-old came undrafted from South Dakota State and signed a one-year, $870,000 deal with Seattle in the offseason last year.
