Cross (ankle) was a limited participant at practice Thursday, John Boyle of the Seahawks' official site reports.
Cross hasn't been able to get onto the field since suffering a high ankle sprain back in Week 7 versus the Chiefs, but he took a big step in the right direction by returning to practice Thursday. With that said, he'll probably need to upgrade to full participation at practice Friday to have a realistic chance at suiting up Sunday at Las Vegas.
