Reggie Bush will retire if he's not signed by end of year

Reggie Bush is seeking a new club, but if he remains unsigned, he will retire at the end of the 2017 season.

Bush, a free agent and last played for the Buffalo Bills during the 2016 season, where he finished with minus-3 rushing yards in 13 games.

"I still want to play, but if it doesn't happen this year, then I'm going to retire," Bush said to ESPN's Michael Rothstein. "I'm not going to miss a whole year and then try to come back for another season at 33 years old, it doesn't make sense."

Although Bush struggled during his tenure with the Bills, he believes he could make a sizable impact as the season progresses. However, he said he'll be selective about any role he potentially takes on.

"I want to play this year. I still feel great. I still feel like I have enough left in the tank to play at a high level, but it's also going to come down to if there's a need for me on certain teams," Bush said. "And then also, if there is a need, it's going to have to be a good fit as well.

"I don't want to go back in a situation just to go back and play. Obviously want to be in a situation where I can obviously be used the right way, be effective, all those different things."

Bush was one of the most prolific collegiate players in recent memory and a two-time national champion at USC. The running back won the Heisman Trophy in 2005, but his award has since been vacated after an investigation determined he received impermissible benefits.

The running back was selected second overall in the 2006 NFL Draft by the New Orleans Saints, and was named an All-Pro punt returner in 2008.
