Positive news on the injury front for San Francisco 49ers

With the injury train seemingly making a stop and filling to the brim with passengers at each San Francisco 49ers’ game, some good news for fans has come out of the Bay Area.

According to a report from CSN Bay Area’s Matt Maiocco, defensive lineman Ray McDonald can continue to play this season with his partially torn right biceps tendon.  The arm will require surgery in the off season.

McDonald injured the arm in the 49ers’  34-3 romp over the Houston Texans on Sunday.  Head coach Jim Harbaugh is cautious about the expected proactivity level for McDonald going forward, but it has to bring a sigh of relief for the organization that already lost defensive lineman Aldon Smith for what appears to be a long, long while and DT Ian Williams to a broken ankle he suffered against the Seattle Seahawks in week two.

“(It’s) hard to predict that right now, how it’s going to affect him the entire season,” Jim Harbaugh said Wednesday, according to the report.

“He feels good about it. The doctors feel good about their evaluation and we’ll trust in that. But (it’s) hard to predict the future on it.”

In addition to Mcdonald being expected to play this Sunday against the Arizona Cardinals, LB Patrick Willis appears set to go as well.  Willis hasn’t played since he injured his groin against the Indianapolis Colts on September 22nd.
