Houston Texans safety C.J. Gardner-Johnson suffered a right leg injury in practice on Thursday and was carted off the field.
Houston television station KRPC2 reported the injury appeared to be to his right knee and an MRI will be done to determine the full extent. He was unable to put weight on the leg before departing, according to the report.
The injury occurred as Gardner-Johnson attempted to tackle wide receiver John Metchie III.
Players gathered around the safety and took a knee as medical personnel helped him on the field at the training camp site in White Sulphur Springs, W.Va.
Gardner-Johnson, 27, is in his first season with Texans, traded by the Philadelphia Eagles after winning Super Bowl LIX last season.
He was listed on the depth chart the Texans released earlier this week
