Lilly allowed five runs on eight hits in three innings during Monday's 12-2 loss. The veteran said he felt tightness in his back and neck during the first inning.
Dodgers manager Don Mattingly said management didn't know Lilly was experiencing discomfort until after Monday's game. The manager would have preferred to know about Lilly's health in advance to allow the club to plan accordingly. The Dodgers used four relievers over five innings before second baseman Skip Schumaker pitched a scoreless ninth.
"That's fine that he feels it, but he's got to let somebody know," Mattingly said before Tuesday's game against the Rockies. "Then at least we know when we go into the game that we possibly should have a guy here that can go four or five innings. He can't just keep that to himself. He hasn't been getting any treatment for it. They've been working on his neck, but that's kind of an ongoing thing with Teddy."
Lilly's neck was an issue in 2012 and he began the season on the disabled list because of it. He returned and won his first five decisions, but injured his shoulder and required season-ending surgery. Lilly started this year on the disabled list and returned to pitch five innings last Wednesday against the Mets, allowing one run. He said he started to feel the neck on Thursday and again while warming up before Monday's start.
Mattingly said Lilly's rib and neck issues are not related, but added the lefty has experienced rib issues occasionally during the past year.
"The injection in the past has taken care of it," the manager said Tuesday night after the Dodgers beat the Rockies, 6-2. "He's got a couple days off and we'll see where he's at."
If Lilly is unable to make his scheduled start Saturday at San Francisco, Matt Magill is likely to replace him. In his Major League debut last Saturday, Magill allowed two runs on four hits with seven strikeouts in 6 2/3 innings.
"That's the logical thing for us to do," Mattingly said.
