The Raiders are keeping A.j.
Allen on the sideline, but his condition is not expected to improve any time soon.
Allen, who tore his left ACL in last Sunday’s loss to the Patriots, is in the hospital with blood clots in the arteries and a damaged heart valve.
Allen’s status is being monitored by Dr. Michael Noll, Raiders team physician.
Raiders owner Mark Davis told reporters that Allen will be released when he’s 100 percent.
He said he hoped Allen would return to the field soon.
The Raiders’ first game of the season is Sept. 6 against the New York Giants.
The Raiders, who are 5-6 without Allen, will need him to be 100 percent for Sunday’s game against the Giants.
Allen has missed seven games this season due to his condition.
Raiders coach Jack Del Rio said last week that Allen would be out “in a week or two” if he’s not cleared.
The injury could make Allen’s return to action a bit more complicated.
Raiders quarterback Derek Carr missed his second straight game last week with a concussion.
The team said it expects Carr to play Sunday.
Allen missed the final two games of last season, his first since his first season with the Raiders in 2007.
