Sullivan was kept out of last weekend’s preseason game vs. Oakland with reported back spasms and was replaced in the starting lineup by journeyman Joe Berger (the word “journeyman” has become permanently appended to his name).
Head coach Mike Zimmer indicated earlier this week that Sullivan’s issue was nothing to be concerned about and the team was just being “cautious” with their veteran center.
