Valdes-Scantling (knee) will be sent for an MRI to evaluate his injury, head coach Brian Schottenheimer said Thursday, Patrik Walker of the Cowboys' official site reports.
Valdes-Scantling suffered an injury at practice Saturday, which has now been revealed to be a knee injury. A return timetable won't be established until the results of the MRI are know, but the veteran wide receiver almost certainly won't suit up for the Cowboys' preseason opener against the Seahawks on Saturday.
