LOS ANGELES -- Lakers star LeBron James has been upgraded from doubtful to questionable for Sunday's game against the Chicago Bulls, the team announced Sunday morning. The Lakers had elevated James from out to doubtful on Saturday.

James is expected to test his foot pregame to see whether he can make his return Sunday, a source told ESPN's Adrian Wojnarowski.

James, sidelined the past 13 games since suffering a tendon injury in his right foot on Feb. 26, tweeted earlier this week that he was working out three times a day to prepare himself for a comeback.

L.A. has gone 8-5 in his absence, reaching .500 for the first time all season with a 116-111 win over Oklahoma City on Friday and climbing to No. 8 in the Western Conference standings.

James, 38, has been sidelined for 27 games this season -- tied for the most games he has missed in a season in his career because of injury.

"Progressing as normal," Lakers coach Darvin Ham said Friday when asked about James' rehabilitation process. "Just doing the work that needs to be done for him to get his foot all the way together."
