The 49ers are suing Aldon Smith.
On Monday, the franchise filed a lawsuit seeking $341,630.18.
The document -- provided by www.scribd.com -- includes the following:
"On August 27, 2016, Smith was suspended for nine games for violating the NFL Policy and Program on Substances of Abuse and the Personal Conduct Policy. As a result, pursuant to the terms of his contract and the CBA, Smith was required to forfeit to the Forty Niners $1,186,027.
"To date, Smith has re-paid the Forty Niners $844,396.82, but still owes the Club $341,630.18."
When contacted by CSNBayArea.com, a 49ers spokesman declined comment on pending litigation. A league source familiar with proceedings of this nature described the suit as procedural when a team receives an arbitration award and the award has not been paid.
The 49ers drafted Smith seventh overall in 2011, and the linebacker was named First-Team All-Pro in 2012.
After multiple off-the-field incidents, San Francisco released Smith in August 2015.
He signed with the Raiders and appeared in nine games during the 2015 season before he was suspended for a calendar year.
The Silver and Black were hoping the NFL would reinstate Smith late in the 2016 season, but the league did not make a decision.
