And here we go.
The Detroit Lions placed tailback Jahvid Best on the physically unable to perform (PUP) list Friday afternoon, defying expectations from all parties that he would be cleared for contact in time for training camp. Players can be activated from the PUP at any time, but unless there is some short-term logistical explanation -- delays in receiving test results, for example -- then there is reason for at least some concern here.
It's been more than nine months since Best suffered the concussion that ended his 2011 season and prompted an extended period of extreme caution regarding his status. Concussion timetables are impossible to predict in an era of heightened scrutiny, of course. But for some time, both the Lions and Best interpreted his progress as an indication that he would be ready for camp.
Maybe they weren't targeting the very first day, and perhaps the Lions have a plan to ease Best into the camp routine over time. But healthy players aren't placed on the PUP list. By definition, Best has not yet fully recovered.
This discussion could be moot within days if Best is activated. If not, however, it's fair to start wondering about his future in this game.
