The Facts: A troublesome knee required Thompson to undergo an offseason arthroscopic procedure.

Diehards Line:An undrafted rookie, Thompson turned an eye-opening training camp into a roster spot. He averaged 5.0 yards a carry on 54 attempts during the season, but a knee and hip injury left him inactive for the final regular season game and the playoffs. General manager John Elway said last week that Thompson, a sturdy 225 pounds, could compete for a fullback spot in Kubiak's offense.
