Martin injured his left knee during Week 1 and did not play last week against the Rams. After rushing for 1,454 yards and 11 touchdowns as a rookie in 2012, he has only played in seven games since the start of last season.
McCoy broke his hand against the Rams on Sunday. He told the Tampa Bay Times earlier this week he is being cautious in his return.
"We're trying to figure out the best way to keep it protected,'' McCoy said Tuesday. "Obviously, it's better if I'm out there but still a long season.
"It can always get worse. That's the risk of going out there Thursday ... time is very short this week, so not having a full week to recover is definitely working against me but I'm a fighter...Most of it is pain tolerance, but as much as you want to be out there, you also want to be smart.''
