NFL.com's Albert Breer reported Monday, per a source, that Wright failed his physical with the 49ers, canceling the trade. Breer reported that the Buccaneers would release Wright, who was arrested on a DUI charge earlier this month. The 49ers had agreed to send a conditional 2014 draft pick in exchange for Wright.
It's unclear why Wright failed the physical, although he had an Achilles injury at one point in 2012. Wright also might be at risk of a league suspension because he also was arrested on a DUI charge in 2012, although that case eventually was dropped.
