Rex Grossman knew his season was over the second it happened.
Chicago's quarterback will miss the rest of the season after rupturing a ligament in his right knee in Sunday's loss to Minnesota.
"In a split second, I knew I was out for the year," Grossman said Monday. "It's devastating."
The young quarterback's loss is a severe blow to a team that has struggled with injuries this season, but managed a 21-10 upset at Green Bay in Week 2.
Backup Jonathan Quinn, who signed with the Bears in March, will start. Chad Hutchinson, who played 10 games two seasons ago with the Cowboys before being waived, also agreed to terms on a two-year deal contingent on passing a physical.
Grossman, a former UF standout, is expected to have surgery in a couple of weeks and will face seven to 10 months of rehabilitation.
"Personally, all I can do is work as hard as I can, do what the doctors tell me to do, get healthy and learn the offense," Grossman said Monday. "(This) just postponed my excitement for playing football for a little bit."
Grossman was injured as he scored on a 6-yard scramble at the 2-minute warning. He left the stadium wearing a brace and using a crutch. An MRI exam confirmed the anterior cruciate ligament tear along with damage to other knee ligaments.
Grossman was the fourth quarterback chosen in the 2003 draft and started the final three games of the season. In Sunday's game, he completed 21 of 31 passes for 248 yards.
He never missed a game due to injury in high school or at Florida.
