James has sat out Cleveland's last six games with the injuries and was not with the team for three games while he was in Miami. Windhorst reports the warm weather was supposed to be beneficial to James' recovery.
Upon returning to the team on Wednesday, James said the weather was part of the reason he is joining the club on its west coast road trip.
"It helps that we're going to some warmer cities, so my body could use that as well," James said. "It's difficult for sure, not being with the guys, and me being a team guy, and a camaraderie guy, it was difficult for sure."
First-year head coach David Blatt said James had not been on the bench because doctors advised sitting for extended stretches could harm his back.
James, who left the Miami Heat to re-join the Cavaliers in the offseason, said he is on track to return next week. He has averaged 25.2 points, 5.3 rebounds and 7.6 assists this season.
Cleveland traded guard Dion Waiters to the Oklahoma City Thunder and acquired guards Iman Shumpert and J.R. Smith from the New York Knicks earlier this week in a three-team trade. The Cavaliers also acquired center Timofey Mozgov from the Denver Nuggets.
The Cavaliers have lost six of their last seven games and have a 19-17 record. They play at the Golden State Warriors on Friday at 10:30 p.m.
