Singletary (hamstring) won't practice Wednesday but is considered day-to-day, Joe Buscaglia of The Athletic reports.
Singletary worked behind Frank Gore in Sunday's 28-14 win over the Giants, taking six carries for 57 yards and a touchdown before bowing out in the fourth quarter. An absence from Singletary in Week 3 against Cincinnati likely would lock in Gore for a heavy workload, with T.J. Yeldon then stepping in as the secondary option. Singletary's practice participation Thursday and Friday should provide a strong clue as to his Sunday availability.
