SANTA CLARA -- Stanford inside linebacker Shayne Skov, who surprisingly went undrafted, has agreed to sign with the 49ers as a free agent.
Skov announced his decision via Twitter, as he refuted an ESPN report that he had decided to sign with the Raiders.
Don't know where the whole Oakland thing came from... But I'm headed to the 49ers, gunna make my mark in this league before it's all over— Gojira ゴジラ Skov (@ShayneSkov) May 11, 2014
The 49ers invested a third-round draft pick on inside linebacker Chris Borland of Wisconsin, the Big Ten Defensive Player of the Year and first-team All-American selection.
Jim Harbaugh recruited Skov to Stanford, where he enjoyed his breakout season in 2010 as a sophomore with 74 tackles, 10.5 tackles for loss and 6.5 quarterback sacks. He sustained a torn ACL and redshirted during the 2011 season.
Skov played in 13 games in 2012 and 14 games in 2013. As a senior captain, he led the team with 109 tackles. He also had 13 stops behind the line of scrimmage and 5.5 sacks.
Borland and Skov are expected to compete against Michael Wilhoite and Nick Moody at inside linebacker while NaVorro Bowman rehabs from a knee injury he sustained in the NFC Championship game. Bowman is expected to miss the first six games of the regular season while on the physically unable to perform list.
