"We're all just playing it by ear and seeing how he feels," Lakers coach Byron Scott said before the game. "I think we'll take it game by game and see how he feels tomorrow and then we'll get ready for Sunday's game."
Scott said that the Lakers' medical staff has not indicated to him whether this is a long-term issue for Bryant.
"They haven't [said that] as of yet, so I take that as, it's not [something] to worry about right now," Scott said.
Rookie Anthony Brown played 22 minutes and scored five points with five rebounds as Bryant's starting replacement at small forward.
The 37-year-old Bryant, who plans to retire at the end of the season, had surgery to repair a torn rotator cuff in his right shoulder last January, an injury that sidelined him for the rest of the 2014-15 season after 35 games.
This season, though, Bryant reported feeling soreness in that shoulder after a Dec. 17 loss to the Houston Rockets, a game in which he threw down a thunderous right-handed dunk. He tore his rotator cuff on a dunk as well.
Following Los Angeles' victory in Boston against the Celtics on Wednesday, Bryant again reported soreness in his shoulder.
"I think now we've got to be a little bit more aggressive to kind of get us through this and go from there," Bryant said, also referencing the team's training staff.
Referencing the Celtics game, Scott said that in the third quarter, Bryant kept telling him, "I just can't get it loose, but I can do other things."
"It wasn't nothing at that time that really affected him as far as his play," Scott said. "But today and yesterday, it probably just stiffened up a little bit more. He just wants to try to get it under control as much as possible before he plays again."
Bryant is averaging 17.2 points, 4.2 rebounds and 3.4 assists in 29 games this season, his 20th in the NBA.
