Vanden Bosch signed a four-year contract with Detroit worth $26 million when he arrived as a free agent before the 2010 season. He quickly earned respect in the locker room, but the price tag may have been too high this year for the 34-year-old.
“Heard they just (released) the one guy that took me under his wing, a great teammate, a great person, my brother KVB,” the message said.
Avril signed a one-year franchise tender before last season, so it’s not clear whether he’ll be back either.
Vanden Bosch has earned three Pro Bowl selections in 11 NFL seasons.
The Lions went 4-12 last season. They released wide receiver Titus Young on Monday.
