The Los Angeles Lakers travel to Detroit tonight to battle the Pistons. They learned earlier this week that they would be without Theo Ratliff for four to six weeks, due arthroscopic surgery on his left knee. Ratliff didn't travel with the Lakers on their road trip, which has stops in Milwaukee (last night), Detroit (tonight), and Minnesota (Friday). Here are tonight's probable starting lineups and busy injury reports for both teams: Point Guard: Derek Fisher Shooting Guard: Kobe Bryant Small Forward: Ron Artest Power Forward: Lamar Odom Center: Pau Gasol Ratliff joins Andrew Bynum as the long-term members of the Lakers' injury report. The good news is that, for the first time all season, Luke Walton and his strained right hamstring are no longer listed on the injury report. Someone who is still listed is Odom, who is probable with a sore right foot, but you can take it to the bank that he will be starting tonight. Point Guard: Rodney Stuckey Shooting Guard: Richard Hamilton Small Forward: Tayshaun Prince Power Forward: Austin Daye Center: Ben Wallace Jonas Jerebko (partially ruptured right Achilles tendon) and Terrico White (broken right foot) are out for Detroit.
