Spence, who recorded six tackles (two solo) in the regular-season finale win over the Browns, finished the 2017 regular season season with 19 tackles (12 solo), including one sack in four games.
After leaving Pittsburgh to play for Tennessee last season, Spence was re-signed after Ryan Shazier (spine) was lost for the final four games. He did an admirable job down the stretch and, though he is an unrestricted free agent, could return in 2018 depending on Shazier's recovery.
Spence totaled eight tackles (six solo) including a sack in Monday's 34-6 win at Houston.
The Steelers needed a big game from Spence with Ryan Shazier (spine) on injured reserve, and the sixth-year linebacker delivered, sharing the team lead in tackles and notching his first sack this season. Spence will be called upon again in Week 17 against Cleveland, as Pittsburgh is still playing for home-field advantage in the playoffs.
The Steelers signed Spence to a contract Wednesday, Teresa Varley of the Steelers' official site reports.
With Ryan Shazier dealing with severe spinal injury and unlikely to play Sunday against the Ravens, the Steelers will bring back Spence, who suited up for 31 regular-season contests with Pittsburgh between 2014 and 2015, to provide some insurance at the second level. Spence played exclusively on special teams in his lone three appearances with the Colts earlier this season, but his familiarity with Pittsburgh's schemes could offer him a better chance at logging defensive snaps in his second stop of 2017.
Spence was released Tuesday by the Colts.
Spence appeared in three games for the Colts this season and was primarily used on special teams. Indianapolis was the third team for which Spence played in the six years since he joined the NFL.
Spence signed a contract with the Colts on Wednesday.
The former Steelers and Titans linebacker had previously signed a one-year deal with the Colts in March, but was cut earlier this month when the team trimmed its roster to 53 men. However, with the Colts having an open spot on the roster when offensive lineman Denzelle Good (wrist) was placed on injured reserve, Spence was near the top of the list of players the organization wanted to bring back. Spence is expected to serve in a depth capacity at linebacker after accruing 54 tackles and three sacks with Tennessee in 2016.
Spence is listed as the fourth-team "WILL" linebacker in the Colts' initial depth chart of the preseason, the Indianapolis Star reports.
Spence signed a one-year free agent contract in the spring and was seen as a potential starter. However, he could be cut this summer since he has just $750,000 guaranteed in his $2.468 million contract.
Spence has agreed to a one-year, $3 million contract with the Colts, NFL.com's Ian Rapoport reports.
A 2012 third-round selection, Spence has started 19 of his 46 regular-season games, recording 144 tackles (100 solo) and five sacks. He's never locked down a role as an every-week starter, but he could get that opportunity with an Indianapolis team that has a clear weakness at inside linebacker.
Spence (illness) was a full participant at Thursday's practice.
Spence apparently only needed to sit out Wednesday's practice in order to get back to full strength. The 26-year-old will likely be available in his normal capacity for Week 17 against Houston as added depth for Tennessee's defense.
Spence was held out of Wednesday's practice due to illness.
It's unclear how severe Spence's illness is at this time. His practice status the next two days will give a better indication of his ability to play against the Texans on Sunday.
Spence (ankle) is listed as active for Saturday's game against the Jaguars.
Spence was unable to play in last week's win over the Chiefs, but he'll return in Week 16. Expect Wesley Woodyard and Avery Williamson to get the start at inside linebacker.
Spence (ankle) was a full participant at practice Wednesday.
The linebacker did not play in Week 15, but coach Mike Mularkey said Tuesday that the team expects to have him back Saturday. This latest news adds credence to that notion.
Titans' coach Mike Mularkey said that Spence (ankle) would likely be back for Saturday's game against the Jaguars, John Glennon of the Tennessean reports.
Spence sprained his ankle in Week 14 and hasn't practiced or played since. Despite that, he's likely making good progress rehabbing the injury and should be considered on the probable side of questionable for Saturday.
Spence (ankle) has been ruled out of Sunday's contest against Kansas City.
Spence's status comes as little surprise after he was unable to practice all week while dealing with an ankle sprain. Nate Palmer will look to see some extra snaps while Spence is sidelined.
Spence (ankle) did not participate in Wednesday's practice.
Spence sprained his ankle Sunday against Denver and is uncertain to be ready for this weekend's game against the Chiefs.
Spence is dealing with a sprained ankle and could miss time at practice this week, Terry McCormick of TitansInsider.com reports.
Look for more updates to come once the practice reports are released this week, as the severity of the sprain remains relatively unknown. Should he miss time, Nate Palmer could see extended reps on the defensive front.
Spence injured his ankle Sunday against the Broncos, ESPN reports.
It isn't clear how severe Spence's injury may be. However, he definitely isn't a lock to be back in time for next week's matchup with the Chiefs.
Spence agreed to terms with the Titans on Wednesday.
A third-round selection in the 2012 NFL Draft, Spence emerged as a key backup for the Steelers the past two seasons, recording 90 combined tackles in 2014 and 2015. He should help on special teams in Tennessee, and he may even compete with Wesley Woodyard for a starting spot alongside Avery Williamson.
Spence failed to record a tackle against Denver on Sunday, and finished the 2015 season with 37 tackles (29 total), including a sack.
Despite playing in just one less game than last season, Spence played 26 percent less defensive snaps, resulting in a decline in production. If Spence, who is an unrestricted free agent, returns to the Steelers next season, he likely finds himself buried behind Lawrence Timmons, Ryan Shazier, Jarvis Jones, James Harrison, Bud Dupree, and possibly Arthur Moats on the linebacker depth chart.
Steelers linebacker Sean Spence totaled eight tackles (five solo) including a sack in the overtime loss to Baltimore on Thursday.
The sack was the first of the season for Spence, and one of five on the night for the Steelers. As a unit, Pittsburgh is averaging three-and-a-half sacks per game, compared to just two per game in 2014.
Steelers linebacker Ryan Shazier (shoulder) has been ruled out for Thursday's game against the Ravens.
Shazier also sat out Sunday's win over the Rams. His absence sets the stage for Sean Spence to see added work in the Pittsburgh defense Thursday.
