Chicago Bears' coach Lovie Smith announced on Saturday that defensive tackle Matt Toeaina will miss the team's Monday night showdown against the San Francisco 49ers with a calf injury.

Toeaina joins quarterback Jay Cutler and defensive end Shea McClellin on the "out" list for Monday's game. Cutler and McClellin were declared out on Friday with concussions. Smith said the rest of the team is doing fine health wise, via ESPN Chicago:

"We have everybody else available," Smith said. "Besides (Cutler, McClellin and Toeaina) we're in great shape."

With Toeaina and McClellin both sidelined, the Bears will dress seven defensive lineman against the 49ers. Chicago will likely activate defensive tackle Amobi Okoye, who has been inactive the last three games. Corey Wootton will probably get a good portion of McClellin's reps at defensive end.

Toeaina has appeared in just two games for the Bears this season, registering three tackles, one solo. The 28 year old played in 12 games last season and 16 the year before, compiling 40 tackles and two sacks combined in the two seasons.
