Denver Broncos first-round quarterback Tim Tebow has passed Tom Brandstater on the team's quarterback depth chart, Mike Klis of the Denver Post reports.

According to Klis, Tebow was the third-string quarterback during today's OTA session, while Kyle Orton received the first-team reps, and Brady Quinn worked with the second unit.

Barring a trade of either Orton or Quinn, Brandstater, a sixth-round pick in 2009, faces long odds to make the Broncos' 53-man roster. The 6-5, 223-pound former Fresno State standout completed 26-of-46 pass attempts for 298 yards and a pair of interceptions during the 2009 pre-season, and spent his rookie season as the team's emergency third quarterback.
