After several false starts to get his NFL career back on track, former Heisman Trophy winner Tim Tebow is getting another shot at playing professional football. ESPN’s Adam Schefter posted on Twitter that the former Denver Broncos quarterback is working out with the Philadelphia Eagles on Monday.

The Eagles have made several curious moves in the offseason, and adding a versatile quarterback to their spread offense is yet another development that many experts didn't see coming.

Head coach Chip Kelly has traded away star running LeSean McCoy, let Jeremy Maclin leave through free agency, traded quarterback Nick Foles to the St. Louis Rams for quarterback Sam Bradford and signed former Dallas Cowboys running back DeMarco Murray. The Eagles also brought back quarterback Mark Sanchez, who was plagued by inconsistency in 2014.

It may be difficult for Tebow to make the 53-man roster, as the Eagles also have quarterbacks Matt Barkley and G.J. Kinnie on the team. Entering the offseason, experts believed the Eagles would consider a trade to land Oregon quarterback Marcus Mariota in the upcoming draft. The possible addition of Tebow may be evidence that the Eagles will continue to explore a variety of options in 2015.

Tebow has never given up on his NFL dream despite drawing little interest after an ill-fated stint with the New York Jets in 2012. The New England Patriots signed Tebow in 2013, but would later cut him after some uneven preseason performances. Tebow was training for a comeback in 2014 even while working as an analyst for the SEC Network, according to an article in the Tennessean.

Tebow was not included on the list of participants in the first-ever NFL Veteran Combine set for March 22, which seemed to signal the end of the chase for a comeback. The former first-round pick apparently still didn’t give up and has been training with a coach who also works with Tom Brady, according to a Newsday report.

The 27-year-old had reportedly improved his throwing mechanics over the past two years. Critics have suggested Tebow's throwing style is a major reason NFL teams have not taken a chance on giving him a roster spot.

The former first-round pick has attempted 361 career passes over his career, registering 17 touchdowns and nine interceptions. His best year was 2011, when he led the Denver Broncos to a playoff win and started 11 games.
