His future with the Tennessee Titans may be more uncertain.
Young, who sustained a thumb injury Sunday before getting into a verbal, locker-room altercation with Titans coach Jeff Fisher, will be placed on season-ending injured reserve, Fisher told reporters late Monday afternoon.
Fisher had told media after the game Young would no longer be the Titans' starting quarterback no matter the injury situation.
Fisher was asked Thursday if Young will ever play for the Titans again.
"We'll deal with that when the season is over," Fisher said.

Young sustained a torn flexor tendon in his right thumb after hitting it on a helmet as he followed through on a throw late in the third quarter of a 19-16 overtime loss to Washington Sunday. He had the thumb wrapped and was throwing on the sidelines, but Fisher opted to stay with third-team rookie quarterback Rusty Smith.
Sources told Jim Wyatt of the Tennessean that Fisher and Young got into an altercation in the locker room, with Fisher telling Young "not to run out on your teammates" when the fifth-year veteran moved to leave.
"I'm not running out on my teammates, I'm running out on you,'' Young replied, according to Wyatt.
Titans owner Bud Adams told Wyatt on Monday that Young will not be released and the incident "will all go away pretty quick."
"It is not anything real serious,'' Adams said.
Fisher told reporters that Smith will start Sunday, with the team planning to sign veteran Chris Simms to be the backup. Kerry Collins, typically the Titans' backup, is recovering from a calf injury.
