In his NFL debut, Thomas had eight receptions for 97 receiving yards and a receiving touchdown as the Broncos defeated the Seattle Seahawks by a score of 31-14.
Thomas's first career touchdown reception came on a 21-yard reception from quarterback Kyle Orton.
He was just the ninth player since 1970 to record at least eight catches in his first game.
Thomas had the second-most catches by a rookie in franchise history, trailing only Eddie Royal, who had nine in a game against the Oakland Raiders in 2008.
The highlight of Thomas's season came when he beat All-Pro cornerback Darrelle Revis for a 17-yard touchdown when the Broncos hosted the New York Jets in a 24–20 loss in Week 6 on October 17.

Thomas was plagued by injuries during his rookie season.
He first missed playing time due to a forearm injury and a concussion; an ankle injury also rendered him inactive for five more games late in the season.

Thomas finished his rookie season with 22 receptions for 283 receiving yards and two receiving touchdowns.
