Muhammad had his suspension lifted Wednesday for violating the NFL's policy against performance-enhancing substances, Aaron Wilson of KPRC 2 Houston reports.
Muhammad was suspended for six games, dating back to last December. The 29-year-old joined the Cowboys on Aug. 1 but was later released on Aug. 29 ahead of their season opener against the Browns. It wouldn't be surprising if he ended up back in Dallas now that he is eligible to play, but he may have other opportunities as well.
