The injury occurred during Golden State's 122-108 home loss to the Jazz on Monday night. Lee underwent an MRI exam Tuesday morning that revealed a nondisplaced fracture of the fourth metacarpal. The team said he will be reevaluated in two weeks.
''Hopefully just a few weeks,'' coach Steve Kerr said before the team flew to Los Angeles, where the Warriors play the Lakers on Wednesday night.
Lee joins a long list of injured players on the depleted Warriors, who are 2-9 following five straight trips to the NBA Finals.
Stephen Curry had surgery on his broken left hand, which he injured Oct. 30, and will need another procedure next month to have pins removed. He said Monday that he expects to be playing again come spring.
The two-time MVP joins Klay Thompson, who is recovering from a July 2 surgery on a torn ACL in his left knee suffered during Game 6 of the NBA Finals. Thompson could miss the entire season.
Kevon Looney, who is dealing with a nerve issue that has kept him out since a brief appearance in the season opener, is going through more extensive workouts but is still not ready to return, while guard Jacob Evans III is still dealing with a strained inner thigh muscle and also will miss Wednesday's game. Kerr said he is likely still at least a couple of weeks from playing again.
Backup center Omari Spellman was listed as doubtful to face the Lakers because of a sprained left ankle and already sat out Monday's loss to the Jazz.
Kerr, who took over coaching the Warriors in 2014-15 and immediately won an NBA championship, has never had this short a bench with so few healthy bodies to mix and match rotations.
''We'll just see how it plays out,'' Kerr said. ''We'll figure out who's ready to go and we'll go from there. It's challenging. It's been kind of the theme so far. It's not exactly ideal but it's the reality. You don't spend a whole lot of time lamenting anything. You just keep going.''
