Tennessee offensive coordinator Mike Heimerdinger is delaying cancer treatment and will call plays in Sunday's game against the Texans. Titans coach Jeff Fisher said Thursday that Heimerdinger met with his doctors Wednesday night and will start his treatment Monday. "So obviously he feels good enough to finish up this week and call the game, so we're very, very excited for that and to have him back and keep him involved," Fisher said. "We're praying for him, and it's been a very, very emotional day, but it's been great to get him back. Guys were happy to see him this morning."
