Roquan Smith was absent from the team’s “bonus” practice on Wednesday.

Smith left the Ravens’ loss to the Pittsburgh Steelers on Sunday with a hamstring injury, and coach John Harbaugh said Monday the team would “monitor” him as he worked to “get ready” for the Monday against the Los Angeles Chargers.

Smith led the Ravens with 13 tackles against Pittsburgh, including two tackles for loss, to add to his league-leading total (110 tackles). Backup linebackers Chris Board and Malik Harrison played a combined 25 defensive snaps in the box Sunday in Smith’s absence, according to Pro Football Focus. Trenton Simpson played 66 of 78 total defensive snaps.

Defensive line Travis Jones (ankle), cornerback Arthur Maulet (calf) and rookie safety Sanoussi Kane (ankle) also missed. Jones was limited to 37 defensive snaps against Pittsburgh, while Kane was ejected from the game late in the fourth quarter. He left the locker room on crutches and in a boot, and Harbaugh said Monday that he is to undergo further evaluation. Maulet suffered the calf injury in practice last week and was inactive for Sunday’s loss.

Safety Kyle Hamilton, who seemed hobbled by an ankle injury against Pittsburgh, was moving without much discomfort Wednesday.

The Ravens’ first injury report for Monday’s game will be released Thursday.
