The Kings said after Saturday's loss to the Warriors that Collison has officially been diagnosed with a left hamstring strain and is considered day-to-day, James Ham of CSN Bay Area reports.

EDGE Analysis

After Collison initially suggested that the hamstring injury would sideline him for several days, it appears that his outlook isn't quite as dire. Collison has already been ruled out for Monday's game against the Spurs, but it's possible he'll be able to return to the court for Wednesday's tilt with the Pistons, if he progresses well in his recovery. James Anderson started at shooting guard in Saturday's loss to the Warriors in place of Collison, and should remain one of the primary beneficiaries of Collison's absence.
