"Last night I took a pretty bad hit from Harrison Barnes and every time I sat down during the game my knees stiffened up a little."
Aldridge, who had his 11th straight game with 20 or more points, also cited some fatigue.
"I thought both guys competed," he said of the matchup. "I was a little tired and I thought he was tired on the second night of a back-to-back."
While fans were expecting Aldridge to come out and make a statement, teammate Nicolas Batum quickly tallied 11 points and five rebounds in the first quarter. Love had 10 points to lead Minnesota, which finished the first leading 29-27.
The Blazers then took off on a 16-4 run, capped by Thomas Robinson's fast-break dunk, to take a 43-33 lead. Williams, who finished with 16 points off the bench, had 10 points in the spurt.
Portland led 65-57 at the break.
Three straight dunks from Pekovic — off feeds from Ricky Rubio — tied the game at 73 midway through the third quarter. But the Timberwolves didn't pull ahead until Martin's 3-pointer made it 79-78 with 3:50 left in the period. The Blazers answered by finishing out the quarter on an 8-2 run to lead 87-81.
Portland pushed its lead to 95-86 on consecutive jumpers from rookie C.J. McCollum.
The Blazers outscored the Timberwolves 60-46 in the paint, and Portland's bench outscored Minnesota's 34-15.
"The second half we just ran out of gas," Minnesota coach Rick Adelman said. "I noticed it. We made runs at them, we caught them in the third quarter, but they kept having one more run."
