TEMPE, Ariz. -- If Bobby Massie plays at right tackle Sunday for the Arizona Cardinals, he won't have much room to make a mistake.

But the fourth-year tackle has accepted that.

Cardinals coach Bruce Arians said Massie will be on a "very short leash" if he starts against the San Francisco 49ers because "Earl Watford [who started the first two games in place of Massie] has played well enough for it to be a short leash."

Massie said Arians' comments won't change how he plays -- if he plays -- Sunday.

"Nah man, it ain't got nothing to do with me," Massie said. "That's what he's giving me. I just have to make sure I go out there and do what I have to do."

Massie missed Arizona's first two games, both wins, for violating the NFL's substance-abuse policy after he was arrested the night before the Super Bowl and subsequently charged with driving under the influence. While he was out, the Cardinals' offensive line did not allow a sack and paved the way for the most rushing yards in Arizona's first two games (235) since 2007 (293).

"It's not like I'm going to go in there and mess up the cohesiveness," Massie said. "Just go in there and hopefully keep the train rolling."

Massie was allowed to spend his suspension around the team, attending meetings and studying his assignments. He just wasn't able to practice, so for the last two weeks he worked on his technique at LeCharles Bentley's offensive line academy in Scottsdale.

Offensive coordinator Harold Goodwin said Massie's mental preparation during the last two weeks was "pretty good." Massie said he wasn't focusing on his arrest or his suspension, adding that he's dealt with all the consequences.

Watching his teammates play without him wasn't easy to handle, but Massie didn't deflect blame.

"It sucked when I was sitting out but I put myself in that situation," he said. "I'm ready to go."

Happy to be back, Massie wasn't sure Thursday who the starting right tackle will be Sunday. But he promised to be ready to if called upon.

"That's not much choice to make. It's all up to the man upstairs," Massie said, referring to Arians. "I'm going to go out prepared like I'm going to start."
