Roger Clemens -- NOT GUILTY in Steroids Case

Roger Clemens was found NOT GUILTY of lying to Congress when he denied using steroids and HGH back in 2008.

In fact, the former Cy Young winner was acquitted on all 6 charges -- including 2 counts of perjury, 3 counts of making false statements and 1 count of obstructing Congress.

Here's the backstory -- a federal panel was tasked with investigating several baseball players in the wake of the Mitchell Report, which connected tons of MLB players to performance-enhancing drugs.

Clemens had been named in the report, but denied using any illegal substances. But Roger's longtime personal trainer Brian McNamee later accused Clemens of lying ... saying he personally injected Clemens with PEDs for years.

Prosecutors believed McNamee and filed charges against Clemens -- but today, a jury found there was not enough evidence to convict Roger on any count.

2:43 PM PT -- Roger just gave a very emotional statement to the media ... thanking his legal team, his family and all of the former teammates that came to his defense.
