The Chicago Bulls are likely to be without their leading rebounder, Joakim Noah, again when they face the Philadelphia 76ers in Tuesday’s Game 5. Noah, who missed Sunday’s Game 4 with a sprained ankle sustained Friday, was still in a walking boot on Monday. Coach Tom Thibodeau said Noah is “most likely out” for Tuesday’s game, a contest the Bulls must win to avoid being eliminated from the postseason. The Bulls trail the Sixers 3-1 in the series. The Bulls are already without last year’s MVP, Derrick Rose, who is out for the season with a knee injury.
