49ers linebacker Aldon Smith has put himself in numerous situations he shouldn't have been in during his young NFL career.

He's had two DUIs and was involved in a fight where he was stabbed at a party at his home in California. He was also arrested recently for allegedly making a false report of a bomb threat at the Los Angeles Internation Airport.

Smith, who had been out of the public eye since his recent legal woe, broke his silence late Monday night, writing a motivational message on his personal twitter account.

"Stay positive and always give your best effort,eventually you will overcome your immediate problems and find you are ready for greater tests," Smith wrote.

The 49ers don't appear ready to give up on Smith as they picked up his fifth-year option, which is worth $9.754 million. In three seasons, Smith has tallied 137 tackles and 42 sacks.
