Tampa Bay defensive tackle Gerald McCoy and St. Louis wide receiver Greg Salas are done for the season.

McCoy, chosen third in the 2010 draft, tore his right biceps Sunday during the opening quarter of a 27-16 defeat to New Orleans. McCoy had just returned to the lineup after sitting out the previous two games because of an ankle sprain.

It’s the second straight year his season ended prematurely because of an arm injury. McCoy missed the final three games of his rookie year with a torn left biceps.

Salas will undergo surgery for a broken right leg. The rookie leads the team with 27 receptions. He was injured when a tackler rolled on him after a 5-yard catch in the fourth quarter of Sunday’s overtime loss at Arizona.

49ers running back Frank Gore injured his left ankle Sunday and had X-rays, which were negative.

Gore, who has five straight 100-yard games, said he expects to practice this week and play against the New York Giants.
