Wes Welker doesn’t sound like he’s ready to give it up just yet. The Broncos receiver’s concussion issues have yielded speculation that he might decide to retire after this season, and the potential to go out on top after Super Bowl XLVIII only makes that notion more enticing. Welker, who turns 33 in May, missed three games due to a pair of concussions this season, equaling his absences in six years with the Patriots. His 73 receptions and 778 yards were his lowest totals since he played for the Dolphins in 2006, but he did have a career-high 10 touchdowns.
