SANTA CLARA -- Despite plenty of speculation suggesting otherwise, the 49ers refrained from making any moves before the league deadline Tuesday.

One national report said the 49ers were "working the phones" as the deadline neared. Speculation heightened when 49ers coach Jim Harbaugh arrived for his weekly news conference 20 minutes later than scheduled.

When asked if there was any news on the trade front, Harbaugh said: "Nothing to report."

A short time later, news surfaced that only one trade happened among the league's 32 teams today.

Coincidentally, the trade involved former 49ers defensive tackle Isaac Sopoaga, who got shipped from the Philadelphia Eagles to the New England Patriots, along with a draft pick, in exchange for a higher draft pick from the Patriots.

Recently, there was a report that the 49ers made running back Anthony Dixon available via trade, given he is in the final year of his contract and the 49ers are on the verge of needing spots on their 53-man roster to accommodate the expected return of several players.

Now that the deadline has passed, the 49ers will have to cut a player for each one that they activate from the non-football-injury, injured-reserve and physically unable to perform lists.

The six players currently on those aforementioned lists are: wide receivers Michael Crabtree and Mario Manningham, running back Marcus Lattimore, defensive tackle Tank Carradine, linebacker Nick Moody and cornerback Eric Wright.

Harbaugh said Carradine practiced Tuesday and that he is expected to be activated soon.
