Outspoken Indianapolis Colts owner Jim Irsay was critical of the offensive line after quarterback Andrew Luck was sacked four times against the Oakland Raiders.

The Miami Dolphins, their next opponent, had six sacks against the Cleveland Browns.

"Raider/Colts-- we gotta protect #12 better..and that includes more than just OL...it's backs,TE's,coaches on blitz pick ups..I DEMAND better," Irsay wrote on Twitter.

"Dolphin/Colts-Make no mistake about it/The Fish CAN and WILL bring the HEAT...We gotta MAN-UP and confront HEAT with a NASA-like Heat-Shield."

Colts coach Chuck Pagano said the team is aware of the need to protect Luck, who was sacked 41 times as a rookie.

"That's every week, you know," Pagano said. "That's [emphasized in] all of our offices and every office up and down the hallway. ... We all know that as long as No. 12 is upright and on his feet, we've got a much better chance of winning with him."
