Okur, who returned from an Achilles' injury two games ago, was injured during pregame warmups Monday.
"He's been looking forward to working himself back in," Jazz coach Jerry Sloan said. "Hopefully it doesn't set him back too much."
Okur ruptured his left Achilles' tendon in the playoffs against Denver last season. The 6-foot-11 forward missed the first 26 games this season before returning last weekend. Okur scored two points in 11 minutes Friday against New Orleans and scored three points with one rebound in 14 minutes against Milwaukee on Saturday.
Okur played in 73 games last season, averaging 13.5 points and 7.1 rebounds.
