Matt Maiocco, of the Santa Rosa Press Democrat, reports San Francisco 49ers S Mark Roman (ankle) returned to practice Thursday, Dec. 28, and took part in full work outs. He is probable for Week 17.

LB Derek M. Smith (hamstring) took part in individual drills Thursday, Dec. 28, but did not take part in team drills. He is questionable for the Week 17 game and would likely be replaced by Jeff Ulbrich if he cannot play.

OLT Jonas Jennings (shoulder) did not practice Thursday, Dec. 28, and was downgraded to doubtful on the team's injury report. OL Adam Snyder is expected to start in his place.
