Brown, who had surgery on the joint in the preseason, practiced Monday and Wednesday and was looking forward to putting on the pads for the first time this season. But he complained of soreness when he arrived at Redskins Park on Thursday morning.
“Obviously, it was a setback because he couldn’t practice today,” Shanahan said. “He was quite sore this morning. We thought he was going to practice. We’ll find out here shortly how big of a setback it is.”
The Redskins have 12 days to decide whether to activate Brown or put him on the season-ending injured reserve list.
Shanahan said he’ll know in the next day whether Brown will need an MRI.
In other injury news, wide receiver Pierre Garçon (foot) and safety Brandon Meriweather (knee) were limited in practice. Practicing fully were: cornerbacks Josh Wilson (shoulder) and DeAngelo Hall (groin), wide receiver Santana Moss (head) and punter Sav Rocca (knee).
