The professional football playing career of quarterback Tim Tebow may have finally come to an end. Tebow, released by the Philadelphia Eagles and head coach Chip Kelly this past weekend, has returned to ESPN as part of their college football coverage on the SEC Nation Show, according to ESPN Sports Business Reporter Darren Rovell.

It seemed as though Tebow had a spot with Kelly's Eagles all but sewn up as the team traded his main competition for the third string role, Matt Barkley, to the Arizona Cardinals on Friday. But when the 4 p.m. Saturday deadline for NFL teams to reach the 53-man roster limit came, Tebow was jettisoned. Kelly, of course, was questioned about the thinking behind his decision and indicated that Tebow simply wasn't "good enough" to man the third quarterback spot and would do well to take his physical talents to a league where he could develop his signal-calling skills - a league such as the AFL or CFL.

"I talked to a little earlier today when we released him," Kelly said Saturday, via NJ.com. "He just needs to get more playing time. Get out there and get actual reps. Because he has done a ton on his own from an individual basis, but it is about taking that next step and playing (in) the game."

It was reported early this week that Tebow had given "very serious" consideration to a move to the CFL in the past. The Montreal Allouettes control his contract rights and even traveled to meet with him during 2014. Tebow, of course, ultimately decided to make a go of it as a commentator for ESPN before giving the NFL one last try this offseason.

Now back at ESPN, it seems the end of Tebow's playing career has come, though it's doubtful he'd agree with such a statement.
