Austin is expected to fill in for Roy Williams who is listed a doubtful on the injury report. Williams suffered bruised ribs during a hit late in the Denver game last Sunday.
Austin has 5 catches this season and one touchdown, but he really hasn't done much the past few weeks.
He told NBCDFW.COM he is looking forward to getting the first start in his pro football career. "It's exciting, Austin said on Friday, "I'm ready to play....I haven't put too much thought into it...I'm not gonna like, write a book about my first day starting ya know, so I'm just gonna go out there and play and give it my all."
Running back Felix Jones and safety Gerald Sensabaugh are unlikely to play on Sunday.
The Cowboys will get a week off after Kansas City which has not won a game this season.
