Lions QB Stafford tweets that he's throwing again

Lions quarterback Matthew Stafford has started throwing again.

Stafford posted a message to his Twitter account indicating he felt good throwing in Athens, Ga., two months after having surgery on his right shoulder.

He tweeted Thursday that he was heading to "rehab, lift and run" during the NFL lockout. He added: "Never know when the owners will let us back in to start playing."

Stafford played in just three games last season. He played in 10 games as a rookie after being drafted No. 1 overall out of Georgia in 2009.

The Lions can receive reports on Stafford's progress, but they are not permitting to make contact with him during the lockout.
