Trubisky didn't practice this week after suffering his injury six plays into the Bears' win against the Vikings last Sunday. The Bears have a bye next week and are hopeful that he can return when they host the Saints on Oct. 20. Backup quarterback Chase Daniel is set to start in Trubisky's place at Tottenham Stadium.
Hicks is set to be a game-time decision once again, coach Matt Nagy said Thursday afternoon. Hicks was sidelined last Sunday after suffering a knee injury in Chicago's win at Washington on Sept. 23.
The Bears also listed guard Kyle Long (hip), tight end Trey Burton (groin) and kicker Eddy Pineiro (knee) as questionable. Linebacker Joel Iyiegbuniwe (hamstring) is doubtful.
Defensive lineman Bilal Nichols (hand fracture) was ruled out. Receiver Taylor Gabriel (concussion) and guard Ted Larsen (knee) are also out after not traveling with the Bears to London.
Kickoff between the Bears (3-1) and Raiders (2-2) comes Sunday at noon CT (6 p.m. GMT) from London. The game can be heard on WBBM Newsradio 780.
