Pau Gasol is expected to sit out for at least two weeks while he heals his strained right groin. The Lakers had initially penciled him out for this week’s trip with stops against Minnesota (tonight), Cleveland (Wednesday and Philadelphia (Friday). Gasol received a platelet-rich plasma therapy injection Monday in hopes to accelerate the healing process in his groin, but the Lakers wouldn’t say what prompted the additional timetable. According to the latest timetable, Gasol will miss at least six more games and won’t return until after NBA All-Star weekend Feb. 14-16, perhaps as early as Feb. 19 when the Lakers host the Houston Rockets at Staples Center. The Lakers haven’t currently set a date on when they will reevaluate Gasol. In addition to the Lakers’ week-long trip, Gasol won’t play in the team’s upcoming homestand against Chicago (Feb. 9), Utah (Feb. 11) and Oklahoma City (Feb. 13).
