The sore plantar fascia Pau Gasol has been managing since Christmas worsened lately but then actually improved the past two days.
Then he said he tweaked it early in the game Tuesday, and it got worse and worse as the game went on, which he said limited his ability to finish moves or shots as he kept coming up short on plays. Then came the big blow.

When Gasol tried to summon shot-blocking vertical as Brooklyn's Brook Lopez drove the lane with 4:21 to play, Gasol felt "a pop" in his right foot.
"Just as I took off," Gasol said, "I felt a pop on the bottom of my foot, on the fascia, and I couldn't get up. ... I'm worried about it."
Gasol said he's "uncertain" now and trying to draw any conclusions before his MRI today in Boston. He said "this is something different" than the plantar fasciitis he has been navigating.
HOWARD 'NOT IN RUSH'
With Gasol suffering what could be a serious foot injury, there is even more urgency for Dwight Howard to play through the pain of a torn labrum in his right shoulder.
The Lakers have won three consecutive games with Gasol starting in Howard's place at center since Howard aggravated his shoulder. By sitting out, Howard is hoping for the pain to subside -- even though the tear is not understood to heal with mere rest.
Howard gave no indication Tuesday if he would play Thursday in Boston.
"It's improving, but I'm not in any rush," Howard said. "I don't want to reinjure it. Got to make sure it heals up."
Lakers teammate Kobe Bryant made his most pointed comments after the Lakers' victory about how Howard has not had many non-debilitating injuries to deal with during his career – and therefore hasn't learned how to manage pain.
"It's a new experience for him," said Bryant, who played 10 playoff games with a torn labrum in 2003.
