The playmaker was limited in practice on Thursday and Friday after sitting out Wednesday's session. Kittle has missed the past two games due to left knee and ankle injuries.
"It went really well," Kittle said after Thursday's practice, via NBC Sports Bay Area. "It was definitely a great step in the right direction. It was really fun being back out there with all the guys. I definitely don't miss sitting in the training room all day. My goal definitely is still Green Bay."
Kittle joins a host of Niners walking-wounded leading up to Sunday night's pivotal tilt versus the Green Bay Packers. The star tight end is questionable to play, as are receivers Deebo Samuel (shoulder) and Emmanuel Sanders (ribs). Meanwhile, RB Matt Breida (ankle) and K Robbie Gould (right quadricep) are doubtful, and DE Dee Ford (quadricep, hamstring) and T Joe Staley (finger) have been ruled out.
"Unfortunately, that falls on the doctors and coach [Kyle] Shanahan, so whatever they decide, I'll do," Kittle said.
Having Kittle back on the field in a tilt that will provide a huge swing for potential playoff seeding for the winner would be gargantuan for the 49ers.
