ARLINGTON, Texas --Cowboys wide receiver Miles Austin has a sore hamstring and did not attend Wednesday morning's walkthrough. Austin had missed some practice sessions last week with a tight hamstring, and he also missed the second preseason game vs. San Diego.
Austin had practiced Tuesday afternoon.
Also, Cowboys linebacker Kenwin Cummings had minor surgery on right thumb to relieve pressure of a severe bruise.
Cummings was wearing a cast during the Wednesday morning walkthrough and he's day-to-day.
Cummings is leading the Cowboys in tackles with nine through two preseason games. Of his nine tackles, seven have been solo.
