It has been a while since we have heard a concrete update on where Detroit Lions running back Jahvid Best stands in his recovery from a season-ending concussion. This may have to do with the fact that there hasn't been much to update, but that was not the case tonight. ESPN's Adam Schefter is reporting that Best has received clearance to work out, and it looks like he will be able to take part in the Lions' upcoming offseason activities.

The source said Best will be able to take part in the Detroit's OTAs, minicamps and training camp. While Best hasn't been cleared to return to football yet, the source would be "shocked" if Best isn't able to fully participate.

Until Best goes through a practice and takes hits, there's no real solid way to tell if he will be able to play in 2012. The fact that he has been cleared to work out is a good sign that he is progressing, though. It's also a good sign that the expectation is for him to be able to give it a go in something like training camp.

Obviously concussions can be very tricky and situations can change instantly, but I'd rather hear promising news like this than something discouraging about the future of Best's career.
