Don't know much about this guy, but he's supposed to fill Turiaf's vacant spot.
From the OCRegister, link is broken so I might not be a done deal:
Lakers spokesman John Black just confirmed that journeyman forward Josh Powell has been signed by the Lakers.
The 6-foot-9 Powell spent the 2007-2008 season with the Clippers, primarily as a backup forward. However, he started extensively late in the season, when starting center Chris Kaman missed 17 of the final 21 games due to an ankle injury.
