Philadelphia Eagles quarterback Tim Tebow has described his opportunity with the franchise as "a blessing".

Sam Bradford is still absent from team drills after suffering a torn ACL last year, leaving Mark Sanchez and Matt Barkley as Tebow's competition for a roster spot.

"I think about it as, what a blessing," Tebow told the media.

"What a great opportunity. I work extremely hard every day, try to be the best teammate I can, the best player. Try to make everybody else around me better as well. All of us are just trying to improve."

Tebow spent two years out of the NFL, working as a college football analyst on ESPN while working on his game to develop his throwing action.
