The 49ers did not activate Michael Crabtree (Achilles') from the PUP list by Monday's 1PM PT deadline, meaning he will not play on Monday Night Football against the Redskins. Coach Jim Harbaugh didn't rule out Crabtree all last week, but this was expected. He was never set to play. ESPN's Adam Schefter reported Monday that Crabtree will almost certainly make his 2013 debut in Week 13. He'll be activated from the PUP list on Tuesday. Crabtree has been sidelined since May 21, when he tore his Achilles' tendon on a pass route in the 49ers' offseason program.
