JACKSONVILLE, Fla. (AP) - The Jacksonville Jaguars have placed quarterback Blaine Gabbert and receiver Laurent Robinson on injured reserve, ending their season.

Gabbert hurt his right forearm in Sunday's loss at Houston. Chad Henne replaced him and threw for 354 yards and four touchdowns.

Gabbert also has a torn labrum in his left shoulder that needs surgery. The Jaguars (1-9) figured it would be better to get it done now.

Nonetheless, coach Mike Mularkey made it clear Monday he was going to start Henne against Tennessee on Sunday based on his performance - not because of Gabbert's injury.

The Jaguars signed Jordan Palmer, who spent the preseason in Jacksonville, to be Henne's backup.

Robinson, meanwhile, sustained his fourth concussion of the season against Houston. Robinson finished the year with 24 catches for 252 yards.
