A year removed from the injury, the 31-year-old Miller is drawing rave reviews from his teammates.
Offensive coordinator Todd Haley said Miller is closer to where he was in 2012, when the tight end had 71 receptions and career highs in receiving yards (816) and touchdowns (8).
"Heath is night and day from where he was last year at this time," Haley said. "He wasn't even ready to go that first game, and it took awhile to get back to where he was close feeling 100 percent. He's 100 percent ready to go. I'm excited to about him being out there for us."
