Derrick Rose's knee continued to feel good two days after appearing in his first game in over 500 days.

“It feels great,’’ Rose said Monday. “I’ve been missing the game for a long time. Just being back on the floor with my teammates and just feeling healthy.’’

“The big thing is last year he practiced from the second half of the season, so we saw that part,’’ Tom Thibodeau said. “And now the next step is obviously the games, and preseason games are obviously different than regular-season games. But just the speed and the explosion are back. Attacking on both ends. And then to see how he responds the next day, to get used to the grind of an NBA season, so that’s the next challenge.’’
