With the 49ers uncertain how much time rookie Reuben Foster will miss, the team reportedly brought in linebackers Sean Spence and Donald Butler for a workout on Tuesday.
News of the workouts was first reported by ESPN.
Spence, drafted by the Steelers in the third round of the 2012 NFL Draft, spent last season with the Titans. In 15 games, he recorded 35 tackles and three sacks.
Butler is a six-year vet with 85 games and 67 starts under his belt. After five seasons with the Chargers, he played for the Dolphins in 2016.
The 49ers are looking for insurance while Foster recovers from a high ankle sprain. On Monday, head coach Kyle Shanahan was unsure when Foster will be back.
“Not exactly sure on the timetable. We'll see how long it takes him.We're going to put him in a boot for a little bit. But those tend to be a month or more. But I can't put an exact date on it," Shanahan told reporters.
Also on Tuesday, the 49ers released linebacker Ben Boulware from the practice squad and replaced him with defensive back Jarnor Jones.
A pair of former Bay Area footballers are headed to Kansas City.
The Chiefs have reportedly signed former 49ers cornerback Keith Reaser and former Raiders running back George Atkinson to their practice squad.
News of the deals was first reported by ESPN.
Reaser was waived by the 49ers on Saturday to make room for cornerback Asa Jackson to be promoted to the active roster in time for Sunday's game in Seattle. Reaser was a fifth-round pick in 2014. After missing his entire rookie as he recovered from ACL surgery, Reaser played in 28 games over the past two seasons. He did not appear on defense in the 49ers’ season-opening loss to Carolina last week, but he appeared on 10 snaps of special teams.
Atkinson has been a familiar face around the Raiders. He was claimed off waivers from the Browns on July 29, but waived on Sept. 2.
San Francisco 49ers assistant coach Katie Sowers has a spot in the Pro Football Hall of Fame in Canton, Ohio.
Sowers, in her role as seasonal offensive assistant, became the first female assistant in NFC history this season. Sowers is situated upstairs for game days as part of Kyle Shanahan’s staff.
Sowers donated her coaching shirt and binder from the Week 1 game against the Carolina Panthers to the Hall of Fame.
“The Pro Football Hall of Fame is pleased that Coach Katie Sowers has donated artifacts from her regular-season debut as the first fulltime female coach in NFC history,” Hall of Fame executive director Joe Horrigan said in a statement.
“Her pioneering role in pro football will undoubtedly inspire others to work to overcome obstacles while pursuing their dreams and aspirations.”
Kathryn Smith, a member of the Buffalo Bills staff last season, was the league’s first full-time female assistant.
