The Cowboys will be without starting safety Roy Williams for the next 3-4 weeks due to a fractured right forearm.  Williams played in both games (1 start) for the Cowboys this season and he has made 6 tackles.  Last season Williams played in 15 games (13 starts) and he finished up with 92 tackles, he defensed 5 passes and he intercepted two passes.  Pat Watkins will replace Williams in the starting lineup for the Cowboys and he has 8 tackles already this season.  He has played in 28 games (9 starts) in his NFL career to date and he has 72 tackles, has defensed 7 passes and he has 4 interceptions.  This will likely hurt the run defense of the Cowboys but help the pass defense.
