As the Los Angeles Lakers look to win their second straight game Thursday night at the Rose Garden against the Portland Trail Blazers, they might be without forward Josh McRoberts. The forward is listed as doubtful for Thursday's game with a sprained left big toe and left thumb.

McRoberts started the first four games of the season with Andrew Bynum serving his season-opening suspension. The 6'10" forward from Duke averaged 6.0 points and 6.3 rebounds per game as a starter, and picked up 10 total points and nine rebounds in his two games off the bench. McRoberts did not play on Tuesday against the Houston Rockets.

Here are Thursday's probable starting lineups in Rip City:

Lakers (4-3)

Point Guard: Derek Fisher

Shooting Guard: Kobe Bryant

Small Forward: Matt Barnes

Power Forward: Pau Gasol

Center: Dwight Howard

Blazers (4-1)

Point Guard: Raymond Felton

Shooting Guard: Wesley Matthews

Small Forward: Gerald Wallace

Power Forward: LaMarcus Aldridge

Center: Marcus Camby

Thursday's 7:30 p.m. PST game will be televised by both TNT and KCAL. For more Lakers news and information, be sure to read Silver Screen and Roll.
