"I'm really ready to play," the fifth-year wideout said at his locker. "It's been a long time coming."
Crabtree was activated off the 49ers Reserve/PUP List this week and will now be added to San Francisco's passing attack in time for the December postseason push.
Crabtree practiced all week and said there was no setback from the Achilles tear he suffered in late May. He's practiced three consecutive days for the past two weeks and felt like his Achilles "responded well" to the training.
"I feel comfortable enough to play," he said. "I feel great."
Crabtree entered the 2013 season with big goals after posting career highs in catches (85), receiving yards (1,105) and touchdowns (nine). After the injury, the play-making wideout made the most of his time by rehabbbing vigorously and watching his teammates closely.
"It's always good to be around the game," he said. "I'm learning from everybody."
In particular, Crabtree picked up a lot of techniques from watching
"I'd be a fool to not steal something from him," Crabtree said.
"I don't want to hype nothing up," he said. "I just want to play ball like I do every Sunday."
Still, the 49ers have yet to have Crabtree and Boldin together on the field in a regular season game. The team envisioned a dynamic pass-catching tandem when they acquired Boldin last March and will now get to see both players in action against St. Louis.
Crabtree said Boldin was somebody he grew up admiring. Crabtree also commended the 49ers for pairing him with great players. In 2012, it was Randy Moss who played next to Crabtree.
With Crabtree back in the fold, the goals for the 49ers remain the same.
"We're gonna need to win," he said. "It's going to take everybody, everybody as a whole."
Crabtree's last on-field performance was in Super Bowl XLVII. He caught five passes for 109 yards and one touchdown in the loss. It hasn't left his mind either.
"We know where we left off last year," he said. "We want to get there."
Crabtree also said his recent practice film is very much like what he put on tape in 2012.
Did it look like the same No. 15?
"Yeah, it did," he said. "That's what made me more comfortable."
