PHOENIX -- For the first time since undergoing surgery to remove a cancerous thyroid on Thursday, Diamondbacks pitcher Doug Davis was with the team on Sunday.
Davis, who was seen in the D-backs' dugout showing his teammates his surgery scar and filling them in on how he's been, lifted the club's spirits immediately.
"To see him in good spirits today is a great story," closer Brandon Lyon said. "It was a touching moment for everybody. We didn't expect to see him this homestand after undergoing [surgery] Thursday."
Davis is expected to need four to six weeks of recovery time before he's back on the mound. But by acting like his normal self on Sunday, the lefty allayed his teammates' concerns.
"With cancer and things like that, in the back of your mind, you just feel like he's got to be in a full body cast or something," catcher Robby Hammock said. "To see him feeling all right was a good sign."
Davis has to take replacement thyroid hormones to substitute for the functions of his thyroid. He is expected to make a full recovery, but because the thyroid plays a key role in regulating how the body burns energy, only time will tell how quickly Davis can recover from his surgery.
For his teammates, though, his appearance on Sunday was a great sign that Davis will be able to make a full return to normal health.
"It put everybody at ease," Hammock said, "and he assured everybody he was all right."
