Linebacker Shayne Skov, who gambled on joining the 49ers as a free agent in May despite an abundance of inside linebackers, was waived from the practice squad today. Also waived was cornerback Chance Casey.
They were replaced by tight end Xavier Grimble, who played against Skov’s Stanford squad at USC, and cornerback Leon McFadden. The 49ers have a shortage of tight ends after both Vernon Davis (ankle) and Vance McDonald (knee) couldn’t finish Sunday’s game. It’s not yet known how long either will be out. Davis was on crutches in the locker room following the game. The 49ers already have a tight end, Asante Cleveland, on the practice squad.
Grimble (6-5, 255) was originally signed as an undrafted free agent by the Giants in May. He spent the offseason and training camp with the Giants before being waived on August 26. McFadden (5-10, 190) originally was taken in the third round of the 2013 draft by the Browns. He appeared in all 16 games (two starts) as a rookie, recording 19 tackles and one pass defensed before being waived on August 30, 2014. McFadden was acquired on waivers by the Jets on August 31 and was later waived on September 11.
Skov, meanwhile, signed as an undrafted free agent in May. And while he played well, he was unable to leapfrog any of the 49ers backup linebackers -- Michael Wilhoite, Chris Borland and Nick Moody -- on the depth chart.
