James, 30, sat out eight games to recover from knee and back injuries before returning last Tuesday against the Suns.
Before sitting out for more than two weeks, James was averaging 25.2 points per game, the lowest mark since his rookie season. In his last three games, however, he averaged 33.7 points, 7.7 rebounds, 5.7 assists and 2.0 steals.
"I know, for me personally, [the two-week layoff] helped me out a lot," James said. "I've felt better in the last three games than I did the whole season, the whole 30-plus games that I appeared in. We've had a 2-1 record since I've been back, so hopefully we can continue on that path."
Fowler also reports that power forward Kevin Love, who is battling a back injury, is questionable for Tuesday's game against the Bulls.
The Cavaliers made a pair of trades during James' absence to shore up the roster. They dealt Dion Waiters to the Thunder in a three-team deal which netted them J.R. Smith and Iman Shumpert from the Knicks, and they also acquired center Timofey Mozgov from the Nuggets.
The Cavaliers are 21-20 on the season and currently hold the No. 6 seed in the Eastern Conference.
