Donald is more likely to debut in Week 2 or Week 3 rather than Week 1, according to Dan Graziano of ESPN.com on NFL Live.
Donald just rejoined the Rams on Sunday, and the team could give him some time to ramp up before tossing him into the mix. Even if Donald does wind up sitting up the opener -- which will be played in nine days against the 49ers in Australia -- that will not have much of an effect on the long-term outlook for the loaded Rams defense.
