Wes Welker has taken a positive step toward an active return to his old stomping grounds.
Welker's status has been unclear since being diagnosed with a concussion that he suffered during Sunday night's 27-17 win over the Kansas City Chiefs. Welker still is working through the league's concussion protocol and must be cleared by an independent neurologist to play this weekend.
Welker spent six hugely productive seasons with the Patriots before leaving the team through free agency in 2013. He enters Sunday with 61 catches for 648 yards and a career-high nine touchdowns.
Some other Thursday injury updates from around the league:
1. Minnesota Vikings running back Adrian Peterson expects to play Sunday against the Green Bay Packers, while scoffing at the suggestion he could benefit from a week off to rest his ailing groin. "I know my body," he said.
3. Shea McClellin practiced for the second consecutive day. The Chicago Bears defensive end has missed the past two games with a hamstring injury but expects to play Sunday against the St. Louis Rams.
