Walker is not in the starting lineup for Thursday's preseason matchup against the Hornets.
Walker got the start against the Grizzlies on Monday, when he posted 15 points, six rebounds and four assists, but he'll retreat to the bench here in favor of Pascal Siakam. As good as Walker has looked in the preseason, he'll open the campaign as one of Siakam's backups at power forward along with Obi Toppin.
