LONDON -- The NFL trade deadline looms in seven days. However, realistically, it’s just a couple of days away for the San Francisco 49ers.

The 49ers are in London preparing for Sunday’s game against the Jacksonville Jaguars (1 p.m. ET, FOX). Thus, if the they plan to acquire someone to play in Week 8, they’d likely have to do it pretty quickly in order to get the player overseas, acclimated to the team, and not to mention, deal with all the logistical obstacles.

But is a trade likely to still happen, despite the logistics?

Well, the 49ers are going to be connected to available receivers until the deadline passes. There have already been rumblings about interest in Cleveland’s Josh Gordon, the Giants' Hakeem Nicks and Tennessee’s Kenny Britt.

One reason the 49ers are reluctant to move forward on a trade is because Mario Manningham will likely soon be activated from the physically unable to perform list and Michael Crabtree is expected back by the end of next month. Though, it still may take Crabtree some time to shake off the rust after tearing his Achilles in May.

This is the second practice week for Manningham, rookie defensive end Tank Carradine and cornerback Eric Wright as they try to transition off of the PUP list. They all must be put on the 53-man roster or be placed on injured reserve by Nov. 5. All three are on pace to be activated by the deadline.

In other 49ers’ notes:

• Coach Jim Harbaugh told San Francisco radio station KNBR that injuries to starting safeties Donte Whitner (knee) and Eric Reid (ankle) don’t currently appear overly serious. That was the indication Sunday night after the win in Nashville.

• Harbaugh told the Sacramento Bee about how he is getting in the spirit of playing in London this week.
