Tim Tebow was released by the Jacksonville Jaguars, ending his bid to return to the NFL after eight years out of the league.

A first-round draft pick by the Denver Broncos in 2010, the quarterback turned tight end thanked the Jaguars for the opportunity following the move Tuesday.

"Thankful for the highs and even the lows, the opportunities, and the setbacks," Tebow, 34, tweeted. "I've never wanted to make decisions out of fear of failure and I'm grateful for the chance to have pursued a dream."
