With the Heat three wins from a league championship, he'll grin and bear it.
Miller was back at practice less than 24 hours after he departed the arena with his left arm in a sling following Miami's victory over Dallas in Game 1 of the NBA Finals.
"It's a little sore, but nothing big," he said.
He did some things with only his right hand on the court, but coach Erik Spoelstra said Miller would be available for Game 2 Thursday.
"There's won't be anything stopping him from playing," Spoelstra said. "In terms of one-handed, he can probably put his guide hand up there if he needed to right now. But we're just trying to rest it."
During the second half of Game 1, Miller winced several times in pain. When asked what caused the injury, he said, "Old age."
No one would blame the 31-year-old South Dakota native for feeling a little creaky. Injuries forced him to miss 41 games during the regular season and three more in the playoffs.
But in the past three games he has averaged 8.3 points and 6.7 rebounds, and he led a strong showing by the Heat reserves in Game 1 of the Finals.
Heat teammate Udonis Haslem is also playing a critical role in June after missing most of the season with an injured left foot.
"It has been tough," Haslem said. "It hasn't been what Mike and I envisioned, but sometimes you get thrown curveballs. The opportunity took longer to come than we anticipated, but it's here now."
Miller sank a pair of 3-pointers in Game 1, including one in the fourth quarter on a feed from Haslem, his former University of Florida teammate.
"It felt like the old days," Miller said. "Unfortunately for us, we haven't been able to have that at all this season."
By far Miller's most worrisome health issue has involved his newborn daughter, Jaelyn, who spent time in intensive care with four holes in her heart. She's much better now.
"It hasn't been easy, but you deal with it," Miller said. "You give it everything you've got and pray that's enough."
