The Cowboys need depth at linebacker with Rolando McClain expected to miss Sunday's game against the St. Louis Rams due to a groin injury. McClain, the Cowboys' leading tackler, is listed as doubtful and did not practice this week.
The Cowboys acquired Edwards on Aug. 30 by trading a conditional 2015 seventh-round pick to the Tennessee Titans.
Dallas owes Tennessee the pick if Edwards is on the Cowboys' 53-man roster for 10 games. The Cowboys are expected to re-sign Edwards.
