SANTA CLARA -- Coach Jim Harbaugh said Monday he does not expect the 49ers to be active at the trade deadline.
The NFL trade deadline is set for Tuesday at 1 p.m. (PT), and the 49ers were a team expected to explore the possibility of making deals. The 49ers have to create roster spots in the coming weeks for the additions of outside linebacker Aldon Smith, nose tackle Glenn Dorsey, running back Marcus Lattimore and linebacker NaVorro Bowman to the 53-man roster.
In other 49ers notes:
--Harbaugh said he has not heard from the NFL whether Aldon Smith’s nine-game suspension could be reduced. “I don’t know anything about any earlier speculation,” Harbaugh said. The NFL could reduce the suspension by a game or two, according to multiple reports. Smith has already served seven games for violations of the NFL's policies for substance abuse and personal conduct
--Nose tackle Glenn Dorsey returned to practice on Monday while on injured reserve/designated for return. Because he went on the list due to a torn biceps, he must miss eight weeks. The earliest he could be eligible to play is Nov. 9 against the New Orleans Saints.

--Running back Marcus Lattimore will return to practice on Wednesday. Harbaugh said the reason to begin the 21-day practice window on Wednesday is so the 49ers are not forced to a make a decision on a game day.
--Cornerback Chris Cook underwent season-ending hamstring surgery on Friday. The injury was so severe there was some bone damage, Harbaugh said.
--Neither NaVorro Bowman (knee) nor Garrett Celek (back) will begin practice this week, Harbaugh said. Both players remain on physically unable to perform.
--Cornerback Chris Culliver returned to full practice on Monday, while nickel back Jimmie Ward was limited.
--The 49ers held photo day after returning after the bye week. Then, for the first time, each of the graduates took a team photo while wearing shirts from their colleges.
