"Dolphins offensive left tackle Jake Long didn't practice Monday and wore a brace on his left knee as he went through pre-practice stretches with teammates. Long rode the exercise bikes after walking over with a slight limp.

Long, one of the offensive line's anchors, suffered an injury to the knee during Thursday's preseason closer in Dallas. The line's other anchor and one of Long's best friends, right tackle Vernon Carey, tumbled into Long's left leg while the leg was planted. Long left the game, but appeared to be walking well afterward.

Lydon Murtha worked at left tackle in Long's place."
