Todd Heap leaves with hamstring injury

BALTIMORE -- Ravens tight end Todd Heap hurt his hamstring in the first quarter of Sunday night's game against the Pittsburgh Steelers and did not return to Baltimore's 13-10 loss.

Heap was targeted on Baltimore's first offensive play. He did not have a catch, but his value to the Ravens was particularly important because he was expected to spend time as a blocker in place of starting fullback Le'Ron McClain, who was out with a sprained left ankle.

Heap entered the game with 37 catches for 546 yards and five touchdowns.
