Broncos fourth-round pick Julius Thomas, a basketball player turned tight end, struggled to get on the field during his rookie season. With Denver adding Jacob Tamme and Joel Dreessen at his position this offseason, Thomas is facing long odds for playing time in 2012.

Thomas hit another roadblock last week when he underwent surgery to repair ligaments in his ankle, according to Jeff Legwold of the Denver Post. The surgery figures to sideline, or at least limit Thomas during post-draft Organized Team Activities.

Thomas finished his first NFL season with one reception for five yards, appearing in just five games. He should make the Broncos’ 53-man roster, but will be hard pressed for significant snaps.
