Welker has missed the past two games after sustaining his second concussion in the past two months. Returning to practice is a positive, but that does not mean he's been cleared for game action.
Here are the rest of the Christmas Day injury updates from around the league:
- The Green Bay Packers didn't practice, but it was an eventful day as NFL Media Insider Ian Rapoport reported Wednesday that wide receiver Randall Cobb, who has been recovering from a broken leg, was very close to playing last week. A source who has spoken to Cobb gives the wide receiver a real chance of returning for Sunday's game against the Chicago Bears.
- Calvin Johnson was one of nine players unable to practice for the Detroit Lions on Wednesday ahead of Sunday's clash with the Minnesota Vikings. Coach Jim Schwartz has said he wants the star wide receiver on the field, if medically cleared, even though his team has already been eliminated from postseason contention. Johnson declined to comment Tuesday when asked about a Deadspin.com report that he's playing through a partially torn PCL in his knee.
