Tom Brady -- Big Papi Is Happy I'm Not Suspended

Tom Brady has some big support coming his way after beating Roger Goodell and the NFL in court on Thursday ... but David Ortiz may be the biggest supporter of them all.

As our friends at BSO pointed out ... Papi posted a tweet after hearing the news of Brady's 4-game suspension being lifted ... showing some Boston love after the New England QB was set free.

Shouldn't be surprised by the support ... both Beantown sports legends are no strangers to championships and controversy ... so they definitely have stuff to bond over.
