ARLINGTON, Texas -- Cowboys safety Gerald Sensabaugh sustained a concussion that knocked him out of Sunday's 34-30 loss to Detroit.
Sensabaugh was bringing wide receiver Nate Burleson to the ground when teammate Anthony Spencer appeared to make contact with the safety's helmet. The medical personnel immediately came to the field, but Sensabaugh was able to make it to the sideline without assistance.
Barry Church replaced Sensabaugh.
The Cowboys have a bye week next week, meaning that Sensabaugh will have extra time to get ready for the Oct. 16 game at New England.
