Washington Redskins starting right tackle Jammal Brown will open training camp on the Redskins’ Physically Unable to Perform list, according to a person with knowledge of the situation.

Brown wasn’t onhand for his team’s first walkthrough and practice sessions of training camp Thursday.

PUP list delegation means a player didn’t pass his training camp physical and hasn’t received clearance to practice. Brown can be activated off the PUP list at any time, as long as he passes his physical.

Brown - who started the last two years for Washington, but ended both seasons in Injured Reserve - has spent the offseason rehabbing his problematic right hip.

Brown had surgery on the hip in 2009, missed the entire season and then was traded to Washington from New Orleans during the 2010 offseason.

Redskins coach Mike Shanahan has said Brown - who re-signed with Washington in 2011 - needs a good offseason to remain on the team.

Brown and his coaches were both pleased with his progress, and said yoga had helped improve his mobility. Brown wasn’t limited in OTAs, but the Redskins have not commented on his absence Thursday afternoon. A spokesman said Shanahan would address it during his post-practice press conference.
