Former Major League Baseball pitcher Roger Clemens pleaded not guilty on Monday to charges of lying about using steroids.
In 2008, Clemens told Congress he had never used steroids or human growth hormones, but his former personal trainer claims he injected the pitcher at least 16 different times.
Before his indictment was handed down, the seven-time Cy Young Winner turned down a plea deal and has promised to fight all charges.
On his Twitter account, Clemens wrote, "I look forward to challenging the Governments accusations, and hope people will keep an open mind until trial. I appreciate all the support I have been getting. I am happy to finally have my day in court."
Clemens could face up to 30 years in prison time and a $1.5 million fine if convicted.
The 48-year-old pitcher has played for the Boston Red Sox, Toronto Blue Jays, New York Yankees and Houston Astros.
