(MCT) — CHICAGO — After the season, the Chicago Bears plan to begin expanding Halas Hall, but they might need to build out the training room now.

In what resembled a last-man-standing battle, they beat the rival Vikings 28-10 on Sunday at Soldier Field, but the badly needed victory came at a steep price. The Bears, who improved to 8-3 by snapping a two-game losing streak, lost five starters and are dangerously thin on their offensive line, depending on the status of guards Lance Louis and Chris Spencer, who both went out with knee injuries.
