Miles Austin out; Kenwin Cummings has surgery

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.

Kevin Ogletree and Dez Bryant ran with the first-team offense.

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.
