The attorney for Reuben Foster's ex-girlfriend says she initially lied to authorities.

Attorney Stephanie Rickard issued a statement on behalf of Elissa Ennis on Wednesday that says her client can prove the injuries that led to the chargers were not caused by Foster.

Foster was charged with three felonies after being accused of dragging his girlfriend and punching her head.

Rickard says those injuries were caused by a fight with another woman and Ennis made the accusation against Foster because he threatened to break up with her.

The 49ers have said they would release Foster if it is proven he hit Ennis.

Mark Sanchez has received a four-game suspension for violating the NFL's performance-enhancing drug policy.

Sanchez acknowledged in an Instagram post Friday that he had tested positive for a banned substance.

"I was blind-sided by the news and I want to say unequivocally that I have never cheated or attempted to gain a competitive advantage by using a banned performance enhancing substance," he wrote.

Sanchez blamed the positive test on an "unknowing supplement contamination." He said he had clean tests 30 days before and 12 days after his positive test.

Sanchez was the No. 3 quarterback for the Bears last season.

The NFL has officially suspended Vontaze Burfict four games for violating the league's policy on performance-enhancing substances.

It was reported in March that the Cincinnati Bengals linebacker was facing the suspension for a failed test on Dec. 27 of last year.

Burfict is expected to appeal based on the fact that he was on prescribed medication for the concussion he suffered on Dec. 4 and a shoulder injury suffered on Dec. 24.

He has been suspended in the past, but for on-field transgressions.

Reuben Foster has been charged with three felonies in a domestic violence incident from February.

Foster is alleged to have “dragged” his live-in girlfriend “by her hair, physically threw her out of the house, and punched her in the head 8 to 10 times,” rupturing her eardrum.

Foster also faces felony charges of forcefully attempting to dissuade a witness and possession of an assault weapon, and misdemeanor possession of a high-capacity magazine in connection with a Sig Sauer 516 short-barreled rifle authorities seized from his home. If convicted of all charges, he could go to prison for nearly 11 years.

The 49ers did not mention any intention to cut Foster in their statement.

“The 49ers organization is aware of today’s disturbing charges regarding Reuben Foster,” the statement reads. “We will continue to follow this serious matter. Reuben is aware that his place in our organization is under great scrutiny and will depend on what is learned through the legal process.”

Foster was the 31st overall pick in the first round last year with his stock falling due to injury concerns and possibly off-the-field issues.
