John Fox has said that the Denver Broncos do not have a "tremendous decision" to make over the future of Wes Welker.

The wide receiver has a season remaining on his contract with the AFC West side, but suffered two concussions during the 2013 NFL season, leading to doubts over his future.

Speaking at the 2014 Scouting Combine in Indianapolis, the head coach told NBC Sports: "Wes Welker is under contract, so I don't think it's a tremendous decision."

Welker had 778 receiving yards and 10 touchdowns during his first season with Denver.
