July 29 (UPI) -- Second-year linebacker Darnell Sankey has signed with the Minnesota Vikings.
The franchise announced the move Saturday and also waived rookie linebacker Shaan Washington.
Sankey spent time in training camp last season with the Denver Broncos. He also participated on the practice squads for the Oakland Raiders and Kansas City Chiefs throughout the 2016 season. He is this cousin of running back Bishop Sankey, who is also on the Vikings' roster.
The Vikings placed Washington on the active/physically unable to perform list on Monday, along with running back Latavius Murray. Washington signed on May 1, along with 12 other rookie free agents.
Sankey's signing comes a day after linebacker Kentrell Brothers was injured in Friday's practice. Brothers was taken off of the field on a cart at training camp in Mankato, Minn.
Washington was waived in order to make room for Sankey. The rookie defender began camp on the physically unable to perform list due to a leg injury.
On Friday the Vikings also agreed to deals with another linebacker in Noor Davis.
Sankey was an undrafted free agent out of Sacramento State last offseason, while Brothers was a fifth round pick out of Missouri in the 2016 NFL Draft. Davis went to Stanford. The Vikings also waived rookie quarterback Wes Lunt on Friday to make room for the Davis signing.
The Vikings' battle at linebacker is one to watch during camp, following the retirement of 10-year veteran and two-time Pro Bowler Chad Greenway.
"Chad was an extreme leader, great guy in the locker room, great guy off the field, great guy on the field, it's hard to describe, you know, what he brought to this football team," Vikings defensive coordinator George Edwards told reporters Friday. "We have a group of young guys at linebackers who don't really have as much experience but they're battling through camp and will continue to battle through camp. Again, we'll look for them to see who's the most consistent every day, take the skill set that they have, adapt them into this game and try to adjust it the best that we can."
The Vikings have their fourth full-team practice on Sunday at Minnesota State University.
