The Las Vegas Raiders placed backup quarterback Marcus Mariota and linebacker Tanner Muse on injured reserve on Monday.
Both players must miss at least three weeks.
Mariota, a former Saint Louis School and Oregon star, signed with the Raiders during the offseason after five seasons with the Tennessee Titans, who made the Heisman Trophy winner the No. 2 pick in 2015.
According to NFL Network’s Ian Rapoport, Mariota has been dealing with a pectoral strain and has been severely limited in recent practices.
Mariota signed a two-year deal in March to be the backup to Derek Carr. Nate Peterman, in his second year with the Raiders, will likely be Carr’s backup until Mariota’s return.
In a corresponding move, the Raiders signed quarterback DeShone Kizer to the practice squad.
In another transaction involving a Hawaii player, the Carolina Panthers have placed former University of Hawaii wide receiver Keith Kirkwood on the reserve/injured list with a broken collarbone.
Under the new league rules, Kirkwood can return to the 53-man roster after three weeks.
Kirkwood played eight games with the Saints in 2018. He did not catch a pass last season in the NFL but was expected to battle for Carolina’s No. 4 receiver spot. Kirkwood played for the Warriors in 2013 before transferring to Temple.
