SANTA CLARA, Calif. (AP) San Francisco defensive tackle Ray McDonald expects to play Sunday when the 49ers host the Arizona Cardinals.
McDonald tore a muscle at the top of his right biceps when he sacked Matt Schaub during the third quarter of Sunday's 34-3 victory over the Houston Texans. He was told he could play with the injury as long as he can stand it.
``It's going to be sore but I should be fine,'' McDonald said. ``I've got all my strength and I'm fine with that.''
The injury for McDonald is the latest in a series of ailments for San Francisco's defensive line this season. Ian Williams went on injured reserve after he broke his left ankle during a loss to Seattle in Week 2.
In addition, rookie defensive tackles Tank Carradine and Quinton Dial are on the non-football injury reserve list, though both could be cleared to start practice shortly.
McDonald and Justin Smith are the only two defensive linemen to start all five games.
``He's one of the toughest guys I know,'' 49ers nose tackle Glenn Dorsey said of McDonald. ``I know that whatever he can do to keep going, he'll do it.''
The 49ers have been able to remain competitive, with Dorsey filling in for Williams and Tony Jerod-Eddie finishing last week's game for McDonald.
``The coaches and scouts go out and find players who can contribute to the team,'' McDonald said. ``Tony did pretty good. He did what he was supposed to do.''
Jerod-Eddie had an interception.
``You have moments like that where you think `That could have been my interception,''' McDonald said. ``We have a saying that we're always happy for another guy's success.''
McDonald said the tear will need surgery following the season.
``I'm able to use it, so that's a good sign,'' he said. ``I'll know more as the week goes on.''
McDonald, in his seventh season, hopes to practice with the team on Wednesday to test the injury.
``You always want a guy like that playing next to you,'' Dorsey said. ``He's a tough guy.''
Like Jerod-Eddie, Dorsey was prepared when his number was called.
``It's about being resilient,'' he said. ``It's about being prepared so that when your time comes, you're ready to play at a high level.''
Carradine, 11 months removed from surgery to repair an ACL tear in his right knee, feels as if he's nearly ready.
``I still have to wait for the say-so, but I am ready to get back on the field,'' Carradine said. ``All I've been able to do is run and lift, so I had no choice but to get better. I've been watching a lot of game film and studying the playbook so I can be up to speed and able to do what I used to do.''
