Tonges (knee) is questionable to return to Thursday's game against the Rams, Nick Wagoner of ESPN.com reports.
Tonges came up limping in the second quarter and was unable to put any weight on his right leg while being assisted off the field by the Niners' training staff. The tight end didn't draw a target prior to suffering the injury. Luke Farrell will be in line for more snaps while Tonges is sidelined.
