Morris, acquired this summer in a swap that sent Avery Bradley to the Detroit Pistons, missed the start of Boston's training camp while on trial for aggravated assault in Arizona. He played in only one exhibition game after being acquitted and the team held him out of game action at the start of the regular season while Morris both got himself in better shape and battled knee soreness.
"Very excited, man," Morris said at Boston's shootaround Friday morning. "This will be a good game for me to come back, anyway. I'm excited to come back."
Morris is expected to come off the bench and will be on a minutes restriction. Celtics coach Brad Stevens also noted that Morris will only play in one game of Boston's upcoming back-to-back against the Orlando Magic and Atlanta Hawks.
"He's ready to roll," Stevens said. "The biggest thing is he's been antsy to play now for a little bit. We wanted to make sure he was making appropriate strides so that when, he does come back, we make sure that he's not going back and forth due to that knee soreness. So hopefully that can be the case."
Morris was projected as a frontcourt starter for Boston before the season and Stevens has used multiple bodies next to Al Horford early in the season. Stevens said the team will let matchups dictate whether Morris eventually shuffles into the starting lineup once he's off his minutes restriction.
Morris marveled at how his season debut will come on the same night that his twin brother, Markieff Morris, is expected to play his first game of the year with the Washington Wizards after undergoing hernia surgery. What's more, both games will be nationally televised on ESPN with the Wizards hosting the Cleveland Cavaliers.
"That's crazy to me," Marcus Morris said. "You got a better chance of hitting the lottery than [twins coming back on the same day]. He goes out with an injury and he comes back and plays a couple hours before me on national television. It's something different."
