Just as the passing game has started to click for the San Francisco 49ers at last, here comes Michael Crabtree.

The team's top wide receiver from 2012 is back on the active roster six months after Achilles tendon surgery and poised to make his season debut Sunday against St. Louis if all goes as hoped during practice this week.

Adding Crabtree to the mix would provide a big boost to a receiving corps that made significant strides in a 27-6 win at Washington on Monday night. Crabtree became Colin Kaepernick's top target last year and had career bests of 85 receptions for 1,105 yards and nine touchdowns.

Mario Manningham continues to impress opposite Anquan Boldin, and Manningham hopes his unit can build off a strong performance and develop some consistency.
