Jared Fogle -- He'll Do Prison Time

Jared Fogle -- who will cop a plea today in his child porn case -- will get prison time as part of the deal ... sources tell TMZ.

As we previously reported, Jared's home was raided in connection with a child pornography investigation and several of his computers were seized by the feds.

We're told child porn charges will come down at the same time the plea deal is announced.

We do not know the length of the prison sentence, but our sources say he will do time.
