Foster decided to retire from the NFL on Monday, Joe Rutter of the Pittsburgh Tribune-Review reports.

EDGE Analysis

The Steelers were likely to release Foster, but he ultimately opted to retire instead. The 34-year-old played all 11 of his NFL seasons in Pittsburgh. All in all, he started 145 of the 160 games he played for the club across his career.

Foster (concussion) does not carry an injury tag for Thursday's divisional tilt against Cleveland, Missi Matthews of the Steelers' official site reports.

EDGE Analysis

Foster sat out Pittsburgh's last two contests due to a lingering head injury, but he's now managed to fully clear the league's five-step concussion protocol. The 33-year-old veteran is on track to draw his usual start at left guard versus the Browns on Thursday.

Foster (concussion) was a full practice participant on Tuesday, Teresa Varley of the Steelers' official site reports.

EDGE Analysis

Foster remains in the concussion protocol, but he is trending in the right direction for Thursday's tilt with the Browns. He has missed two games with the issue.

Foster (concussion) has been ruled out for Sunday's game against the Rams, Teresa Varley of the Steelers' official site reports.

EDGE Analysis

Foster will miss his second straight game after entering the concussion protocol prior to Week 9. Matt Feiler, the Steelers' usual right tackle, will slide over to left guard in Foster's stead.

Foster (concussion) has been ruled out for Sunday's game against the Colts, Brian Batko of the Pittsburgh Post-Gazette reports.

EDGE Analysis

Foster suffered the concussion during Monday's win over the Dolphins, so it's not a major surprise he wasn't able to clear the concussion protocol in the last few days. B.J. Finney is likely to take over at left guard for the Steelers.

Head coach Mike Tomlin said Tuesday that Foster is currently in the concussion protocol, Brooke Pryor of ESPN.com reports.

EDGE Analysis

Tomlin also noted that it's unclear when Foster will be available. The 23-year-old sustained the injury in Monday's matchup with Miami.

Foster is questionable to return to Monday's game against the Dolphins while he gets checked for a concussion, Brian Batko of the Pittsburgh Post-Gazette reports.

EDGE Analysis

It's unclear when Foster picked up the injury, but out of halftime, he won't make an appearance on the field. The Tennessee product will have to clear the league's mandated concussion protocol before granted re-entry. In his absence, B.J. Finney has taken over at left guard and should continue to do so as long as Foster is sidelined.

Foster signed a two-year, $8.25 million deal with the Steelers on Thursday, Gerry Dulac of the Pittsburgh Post-Gazette reports.

EDGE Analysis

Foster started all 16 games for the Steelers last season and has missed only four games over the last four seasons, so it's unsurprising the team wanted him back on a short-term deal. The 33-year-old will likely remain at left guard for the Steelers in 2019.

Foster (knee) was a full participant at Thursday's practice.

EDGE Analysis

Foster sustained the injury in Sunday's loss to the Chiefs, but ultimately wasn't forced to miss any practice time. The 32-year-old should be at his post at starting right guard for the Steelers on Monday.

Foster (knee) sustained a knee injury in Sunday's 42-37 loss to the Chiefs, Ed Bouchette of the Pittsburgh Post-Gazette reports.

EDGE Analysis

It remains to be seen whether Foster's current injury is related to the bone bruise he spent the offseason nursing. With Marcus Gilbert (hamstring) also recovering from an injury, Pittsburgh's offensive line enters Week 3 surrounded by question marks. If Foster were to miss any time, B.J. Finney would step in for him at the left guard position.
