Vince Young, a former Tennessee Titans quarterback and currently an unwanted free agent, will work out Wednesday with the Bills in Buffalo.
The team's website, buffalobills.com, broke the news Tuesday afternoon.
Young, who turns 29 in two weeks, was the third overall draft pick in 2006 after a dazzling college career at the University of Texas.
"Young is being viewed strictly as a potential backup quarterback option for the Bills," the website said.
That is, as a backup to entrenched starter Ryan Fitzpatrick.
In five seasons in Tennessee, Young's performances were inconsistent and prone to being scattershot, only occasionally showing flashes of his college brilliance.
Lean and long-legged at 6-foot-5, Young did earn AFC rookie-of-the-year honours in 2006. And he was chosen by the Sporting News as the NFL's comeback player of the year in 2009, after injuring a knee in 2008.
But Young again struggled in 2010, and was benched after a heated argument with then head coach Jeff Fisher. The Titans released him last July.
The Philadelphia Eagles signed him to a one-year contract for 2011 to be a backup to Michael Vick. When Vick was injured, Young started three games last fall and struggled, completing 58% of his passes for only four TDs against nine interceptions.
Between bonuses and salary, Young earned $4 million with the Eagles.
Philadelphia chose not to re-sign him this year, and he became a free agent March 13.
In Tennessee, Young's TD/interception ratio improved as his career progressed. Whereas it was a horrible 21/30 after his first two seasons it was 20/10 over his last two seasons, 2009-10.
Young is 31-19 in his career as a starter.
Tyler Thigpen was the backup to Fitzpatrick last year but barely played. He is still under contract.
