"We're in a rough patch right now," Lillard said. "We're not shooting the ball very well and we've got to defend better. We've played so well, we were due for a rough patch and a little bit of adversity."
Wesley Matthews had eight points on 2-of-9 shooting for Portland, which had a five-game home winning streak snapped.
"We're fine. We know we weren't going to go undefeated this season," Matthews said. "We knew we were going to lose games. It's just our job to minimize the losses, stop the bleeding and get back to our winning ways."
The Blazers enter this contest after three days off, while Toronto comes in playing the second of a back-to-back after Friday's 100-90 win over Denver. Portland has won five straight home meetings with the Raptors.
"We've played a lot of games lately. We've done a lot of traveling. No one likes to use fatigue or the schedule as an excuse, but it is a reality," coach Terry Stotts said. "We need to catch our breath, get our bodies right and be ready to play Saturday."
Toronto (25-21) is a season-best four games above .500, winning three straight and five of six. DeMar DeRozan scored 19 points and Terrence Ross added 18 against the Nuggets to begin a five-game West Coast road trip.
The Raptors' 25-point lead dwindled, but they held on for the win.
"We will take the `W,' but it was not a quality finish," coach Dwane Casey said. "I let the players know I was disappointed in the close. You can't come in and feel like you have the game won with a 20-point lead. You have to continue to execute, be strong with the ball and continue to execute defensively if you want to be serious about winning in this league."
"We have to finish a lot better," Lowry said. "This is the NBA. Teams are going to make a run. We're not going to be negative. We won the game. But we have to finish better than that."
Toronto scored four points in the last 35 seconds of regulation to tie the last meeting with Portland, but Aldridge and Lillard had 25 points apiece to help the Blazers pull out a 118-110 overtime win Nov. 17.
The Raptors haven't won in Portland since Dec. 22, 2006.
