Here are a few injury updates from Lions head coach Dan Campbell, including the latest on Alex Anzalone and Graham Glasgow.

If Detroit Lions offensive guard Graham Glasgow can't play Sunday, rookie sixth-round pick Christian Mahogany could get his first career start.

Graham Glasgow has played every offensive snap through the Lions' first 14 games, making starts at center and left guard

Glasgow (knee) was a full participant in Thursday's practice. The starting left guard had to miss Detroit's 34-17 win over Chicago last Sunday with the knee issue, but he was able to practice in a limited capacity even on the Friday before that game.

Mahogany started in place of Graham Glasgow, who was out with a knee injury. At this present juncture, coach Dan Campbell expects Glasgow to recover his post at left guard for Monday's game against the San Francisco 49ers.

The Detroit Lions will be without multiple offensive linemen against the Chicago Bears on Sunday, including right guard Graham Glasgow.The lineman was previously listed as questionable before Sunday's final inactive report.

Cornerback Terrion Arnold returned to practice after missing on Thursday with an illness. Running back David Montgomery remained out with a knee injury. Starting left guard Graham Glasgow was also on the field for the second consecutive day after missing last week's game with a knee injury.

The Lions had already ruled out two players due to injuries. Running back David Montgomery and linebacker Jalen Reeves-Maybin will not play, as expected. Reeves-Maybin technically still remains on the injured reserve, so he’s not a designated inactive for this game.

Graham Glasgow will return to the starting lineup Monday against the 49ers, but Christian Mahogany played well in his first NFL start.
