Asked about the sore back that has been bothering Bryant since the opening moments of Game 3, Jackson said, "I think he'll have no problem. He came out and shot with the rest of the players."
Bryant's health has been a key factor in the best-of-seven series, which the Lakers can close out with another victory. They take a 3-2 lead into Game 6.
According to Jackson, the Lakers are confident.
"We've done well here," he said. "We know we can win here."
Including the playoffs, the Jazz have lost only five games at home all season. But the Lakers were close in Games 3 and 4 of this second-round series, losing 104-99 and 123-115 in overtime.
"Predictions are right about the playoffs," Jackson said. "Intensity builds from game to game. You know it's going to be a wired game [tonight]. There will be a lot of energy in the building. Players will play real hard. We just anticipate we will have to play under control and have to execute, especially in a foreign land like this."
Jackson paused before quickly adding, "A foreign building."
The Lakers have shot at least 37 free throws in four of the first five games against Utah, and Jackson expects another physical battle.
"I think the physicality is probably par for the course as far as playoff basketball, which is two or three times greater than the regular season," he said. "I think the referees are trying to do their best job as far as trying to mete out what is appropriate and keep things on an even keel throughout the game. But it is physical. It's very physical under the boards and we're going to have to play a physical game."
