Los Angeles Chargers star linebacker Joey Bosa aggravated a hip injury in the first quarter of Sunday’s meeting with the Pittsburgh Steelers and is questionable to return.

Bosa dealt with the issue throughout the week, turning in limited practices on Wednesday and Thursday before participating in full on Friday.

Prior to his departure Sunday, Bosa had not recorded a tackle.

Bosa, 29, logged two sacks and nine tackles through Los Angeles’ first two games of the season. He is a four-time Pro Bowl selection.
