76ers forward Elton Brand practiced with the team's second unit on Monday.

Philadelphia has been forced to undergo some lineup changes with second-year forward Marreese Speights out with a knee injury.

Jason Smith was running with the first team, according to the Philadelphia Inquirer.

"We went through a normal practice today and we always change our lineups in practice. Certainly [Jason] Smith will get more time at center. Elton will get some time at center and Primoz will be activated so we think we're pretty well covered," coach Eddie Jordan said of the practice rotation.

Jordan added that Brand was playing center with the second unit and smiled when asked about lineup changes heading into Wednesday's game against the Bobcats.
